To minimize cost and ensure safety, nanocomposites must be prepared without flammable or explosive solvents at room temperature and ambient-pressure drying. However, fabricating resin aerogel nanocomposites is challenging due to the tendency of porous structures to collapse owing to the complex surface tension in the multiphase system of fibers, resin particles, and solvent. A novel quartz fiber-reinforced hybrid aerogel nanocomposite is successfully prepared using the sol–gel method with self-assembly template polymerization. Two key factors in preventing aerogel collapse include the use of a cationic surfactant as a stabilizer for the initial template and as a surface tension improver during drying. The nanocomposite, with a density of 0.52 g·cm−3 and thermal conductivity of 0.046 W·m−1·K−1, exhibited a back-face temperature rise of ≈96.4 °C after a 1500 s arc-wind tunnel ablation test. The maximum ablation retreat is ≈0.26 mm. This novel nanocomposite shows potential for high-temperature protection systems in extreme oxidation environments.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 3","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400291","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this need, a cellulose-based smart fluorescent material (NCC@NH2@RB) with a conjugated structure is designed and synthesized for the rapid and sensitive detection of Fe3+ ions. This sensor features core-shell nanoparticles functionalized with rhodamine B (RB), using (3-aminopropyl)triethoxysilane (APTES) as a linker. The resulting fluorescent probe, composed of nanocrystalline cellulose and RB, exhibits strong fluorescence under ultraviolet light, making it an effective tool for Fe3+ ion detection in water. When Fe3+ ions are introduced into a solution containing NCC@NH2@RB, they bind with weak-field ligands such as nitrogen and oxygen in the probe's structure, forming complexes. This interaction involves high-spin coordination and leads to the self-assembly of Fe3+ ions on the surface of NCC@NH2@RB. The process generates single electrons, increasing paramagnetism and quenching the fluorescence. The NCC@NH2@RB fluorescent probe has a limit of detection (LOD) of 0.01 µM and a limit of quantification (LOQ) of 0.03 µM with linearity at concentrations of 1.0 × 10−4–2.5 × 10−3 m. This fluorescence quenching effect is specific to Fe3+ ions, ensuring that the probe remains unaffected by other metal ions.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 2","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400285","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is synthesis of polydopamine (PDA) nanocapsules and analyze the adsorption and release properties of doxorubicin (DOX). PDA nanocapsules are manufactured using hard template approach. The influence of various parameters such as pH, adsorption time, and initial DOX content on the adsorption and release process is investigated. The resulting adsorption isotherm is consistent with the Langmuir isotherm, indicating that DOX adsorption on PDA nanocapsules is homogenous, uniform, and monolayer. PDA nanocapsules have an adsorption capacity of 689.6 mg g−1 under alkaline conditions, which is attributed to phenol group deprotonation mechanism and electrostatic repulsion. The adsorption kinetics are more consistent with the pseudo-second-order model. Furthermore, raising initial concentration of DOX results in a greatly increased adsorption capacity due to a larger driving force. Among the several parameters that can influence the pace and degree of DOX loading and release, local pH is regarded as a significant environmental component in the processes. Thus, pH-responsive PDA nanocapsules have a significant potential for usage in locations with aberrant pH level, such as cancer tissue.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400261","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143116072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary hydrogel network comprises Pluronic P123, while the secondary network comprises gelatinmethacrylate (GELMA) and polyacrylamide (PAM). A systematic approach is adopted to develop DN hydrogels. Initially, the impact of Pluronic P123 concentrationon the mechanical properties of PAM-GELMA hydrogel is investigated. Results from the tensile strength and the oscillatory shear tests reveal that an increasing P123 concentration has a marginal effect on the storage modulus while significantly reducing the loss modulus of the PAM-GELMA hydrogel, thereby improving mechanical properties. Notably, DN3 hydrogel containing 7.5w/v% P123 in PAM-GELMA exhibits osteoid matrix-like mechanical properties. To further enhance the mechanical properties, citrate-containing amorphous calcium phosphate (ACP_CIT) is incorporated in DN3 hydrogel at varying concentrations. At a lower concentration of ACP_CIT (0.75 w/v%), the mechanical properties of DN3-ACP0.75 hydrogel are notably enhanced. Incorporating ACP_CIT in DN3 hydrogel (DN3-ACP0.75) decreases creep strain, rapid stress relaxation, and reduced water uptake capacity while maintaining the thermoresponsive behavior. Finally, an in vitro analysis confirms the cytocompatibility of the hydrogels with MC3T3-E1 cells, indicating the potential use in bone tissue engineering.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"309 12","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400177","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142861134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving a balance between high mechanical strength, electrical conductivity, thermal conductivity, and electromagnetic interference (EMI) shielding remains challenging. In this study, a dual-processing strategy combining Pickering emulsion templating and melt blending is presented to hybridize 1D carbon nanotubes (CNTs) and 2D graphene nanoplatelets (GNPs) within a PLA matrix. This approach successfully forms a stable dual-filler network, ensuring uniform dispersion of the fillers. The results show that this method significantly enhances the performance of the resulting PM-PGxCy composites (P: Pickering emulsion; M: melt blending; x and y: mass fractions of GNPs and CNTs, respectively). Specifically, the PM-PG1.43C1.43 composite exhibits remarkable improvements in mechanical strength (56.2 MPa), electrical conductivity (43.5 S m−1), EMI shielding effectiveness (20.1 dB), and thermal conductivity (0.34 W m·K−1), outperforming composites prepared using either method alone. These findings indicate that the dual-processing strategy effectively combines 1D and 2D fillers, facilitating superior interfacial interactions and enhancing the multifunctional properties of PLA-based composites. This study offers a new approach to achieving high-performance PLA composites with low filler content, offering significant potential for applications in electronics, packaging, and EMI shielding technologies.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 3","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400306","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143602490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
