While cationic polymers are promising gene carriers, they suffer from an inherent trade-off between transfection efficiency and cytotoxicity: high nitrogen-to-phosphorus (N/P) ratios can enhance gene delivery efficacy but inevitably increase cellular toxicity due to excess free cationic polymers. Here, we report a fluorinated polymer that achieves potent gene transfection at an unprecedentedly low N/P ratio below 1. Mechanistic studies demonstrate that the obtained polymer completely condenses DNA into stable nanoparticles at an N/P ratio around 0.4, with negligible unbound polymers remaining in the polyplexes. Detailed intracellular trafficking analysis revealed that the polymer/DNA complexes are primarily internalized via scavenger-receptor-mediated endocytosis, followed by rapid endosomal escape and efficient nuclear entry within 4 h. The polymer successfully delivered multiple protein-expressing plasmids across diverse cell lines, demonstrating broad applicability. Our findings establish this fluorinated polymer as a novel class of highly efficient gene vectors that function without requiring excess free cationic polymers. This study provides valuable insights for the rational design of next-generation gene delivery systems with enhanced efficiency and minimized cytotoxicity.","PeriodicalId":14443,"journal":{"name":"International polymer science and technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147913830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the underlying mechanisms behind these properties and its interactions with water molecules remain insufficiently understood, which limits its broader application. In this paper, by employing atomic force microscope-based single-molecule force spectroscopy (AFM-SMFS), the single-chain behaviors of PEtOx in different environments have been investigated, revealing a reduced extensibility observed in deionized (DI) water and KCl solutions of low concentrations (≤ 0.1 M) compared with that in nonane. Gel electrophoresis results indicate that PEtOx is positively charged under these conditions. These findings indicate that PEtOx exhibits polyelectrolyte-like behavior in DI water: (i) an increased stiffness compared to its inherent elasticity; (ii) a directional migration of polymers under the electric field. The possible reason for the polyelectrolyte-like behavior could be that the PEtOx chain is charged due to H-bonding with H3O+. These findings suggest that PEtOx is another pseudo-polyelectrolyte (or supra-polyelectrolyte), similar to PEG. Given that proteins and nucleic acids are polyelectrolytes, it is reasonable to infer that the polyelectrolyte-like behavior of PEtOx may be one of the reasons for its good biocompatibility. It is anticipated that this discovery will lay the groundwork for further applications of PEtOx in biomaterials.","PeriodicalId":14443,"journal":{"name":"International polymer science and technology","volume":"2 4","pages":"248-257"},"PeriodicalIF":0.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147894228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the typical high performance polymer (HPP) materials of poly(arylsulfones) and poly(aryl ketones), each capable of achieving transparent-to-multicolored variations, are taken as the breakthrough point, and ingeniously coupled with the conductive substrate modification layer (SnO2) and the ion storage layer (V2O5), to construct electrochromic supercapacitors (ECSs) capable of fully unlocking the extraordinary intrinsic performances from the active substances. SnO2 nanosheets were utilized to construct the microstructure of the active layers with uniform porosity with a view to improving the response speed of the system in response to the input electrical signals. Alternatively, modified V2O5 nanowires, which were highly compatible with the EC materials and did not interfere with their color-changing effect, were specially identified as the counter electrode materials to facilitate the specific function. Benefiting from the porous composite structure, the delicately matched poly(bis(4-(diphenylamino)phenyl)sulfone) (P-TST) device with P-TST@SnO2/V2O5 structure boasted an optical contrast ratio of 68.07%, a reduction in coloring time by more than 2/3, and a near-doubling coloration efficiency. Additionally, the construction strategy is beneficial to the capacitive properties as well. There is a perfectly adequate compatibility between material variety and multi-functionality. Such an alternative and versatile construction strategy is justified to inject vitality into the development of electrochromism in multifunctional smart windows or displays.","PeriodicalId":14443,"journal":{"name":"International polymer science and technology","volume":"1 9","pages":"787-798"},"PeriodicalIF":0.0,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147912589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exposure to UV filters may directly result in serious health problems, such as skin penetration, cytotoxicity and the production of carcinogenic reactive oxygen species (ROS). Here, organic UV-filter self-framed microparticles (SFMPs) were developed, in which a small organic UV filter, antioxidant and hexachlorocyclotriphosphazene were self-assembled into microparticles by one-pot precipitation polycondensation without any vehicles/carriers. The resultant SFMPs could prevent UV irradiation and have strong ROS scavenging ability, while significantly reducing skin penetration. Furthermore, incorporating small molecules into the microparticles can prevent direct contact between the epidermis and the small UV filter, overcome the problems of self-instability and poor solubility of the antioxidant, and solve the issue of nanoparticle aggregation. Moreover, SFMP microparticles exhibit attractive UV-shielding performance in vivo and in vitro without toxicity. Therefore, we speculate that the self-framed SFMPs with outstanding ROS scavenging ability and excellent UV protection performance will have a promising application in the field of sunscreens.","PeriodicalId":14443,"journal":{"name":"International polymer science and technology","volume":"1 8","pages":"716-726"},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, organic-inorganic biomass composite aerogels with ablative properties are fabricated by a straightforward and environmentally friendly ambient-pressure-dried method, utilizing gellan gum, hollow glass microspheres, and phenolic resin. This method uses air bubbles as pore templates for constructing aerogels without additional modification or organic solvent consumption. The robust cross-linking networks formed within the aerogels significantly mitigate volume shrinkage induced by surface tension during mild drying while endowing the aerogels with a high modulus of 37.8 MPa and robust resistance to diverse rigors. Remarkably, upon exposure to high temperatures or fire, it spontaneously transforms into ceramic-like hybrid char with low volume shrinkage, continuous pore structures, and high stability. The ablative property of these aerogels enables them to maintain a high modulus of 8.22 MPa even after being treated at 900 °C, while also exhibiting excellent high-temperature insulation, flame retardance, and smoke suppression. This work provides a facile and ecofriendly way for developing advanced hybrid biomass aerogels that combine high stiffness with superior thermal protection across a wide temperature range.","PeriodicalId":14443,"journal":{"name":"International polymer science and technology","volume":"1 6","pages":"551-562"},"PeriodicalIF":0.0,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Underwater self-healing materials offer significant advantages by autonomously repairing damage in-situ during operations, thereby minimizing resource waste and enhancing environmental sustainability. However, most self-healing materials do not have sufficient stability in aquatic environments due to the presence of water-sensitive weak cross-linking bonds. Herein, polysulfide elastomers capable of underwater self-healing have been developed through a straightforward, one-step thiol–ene click reaction strategy. This reaction can occur in-situ underwater due to its water insensitivity. The abundance of disulfide bonds in the elastomer enables the formation of coordination bonds with metals, endowing the material with outstanding underwater metal adhesion properties. The optimal elastomer LPTM-55 shows extraordinary toughness of 1.49 MJ/m3, underwater self-healing efficiency of 90% within 7 h and adhesion strength up to 1.2 MPa. This innovative material, characterized by its underwater curing, adhesion and self-healing capabilities, demonstrates significant potential for applications in underwater sealing and repair.","PeriodicalId":14443,"journal":{"name":"International polymer science and technology","volume":"1 5","pages":"458-467"},"PeriodicalIF":0.0,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147913051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the integration of numerous functional applications in the biomedical field still presents notable challenges. In this research, a rigid hard-structured network was formed by cross-linking gallic acid grafted chitosan (CS–GA) and tannic acid (TA) with poly(vinyl alcohol) (PVA) through physical freezing. The noncovalent hydrogen bonding during the freezing and thawing process facilitated the formation of microcrystalline domains in the amorphous hydrogel network system. Functional proteins from eggshell membrane were cross-linked with tetra-armed poly(ethylene glycol) maleimide (4am-PEG-MAL) via thiol-olefin click chemistry, and lysozyme was incorporated into the network as an antibacterial component through the nucleophilic substitution reaction. These chemical cross-linking methods resulted in a soft-structured network that enhanced the mechanical properties of the hydrogel (maximum stress of 2.15 MPa and elongation of 605%). The use of ionic liquids/ethylene glycol/water (ILs/EG/H2O) ternary solvents instead of a single solvent not only provided frost resistance but also imparted excellent electrical conductivity to the hydrogels (0.37 ± 0.04 S/m). Notably, the organohydrogel showed good antimicrobial properties and biocompatibility and was effective in providing emergency cooling after fireworks burns and promoting wet healing of broken skin to minimize scarring. In the biomedical field, this multifunctional hydrogel can serve as a flexible wearable device to monitor the movement amplitude of wounds in real-time, offering a novel approach to deep learning-assisted wound healing. The multifunctional nature of this organohydrogel as a flexible wearable device in the biological field presents promising applications.","PeriodicalId":14443,"journal":{"name":"International polymer science and technology","volume":"1 3","pages":"245-260"},"PeriodicalIF":0.0,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
