Their notable characteristics, including high mechanical strength, superior adhesiveness, exceptional water retention capacity, and antibacterial properties, offer innovative solutions for numerous challenges faced in the biomedical field. In this study, tannic acid (TA) was employed as a crosslinking agent, and mixed solutions of water and glycerol with different mass ratios were adopted, resulting in the successful synthesis of a polyvinyl alcohol (PVA)/gelatin (GEL) organic hydrogel with remarkable mechanical properties. The incorporation of TA facilitates the formation of robust hydrogen bonds with the PVA chains, thereby enhancing the mechanical strength of the hydrogel. The maximum tensile strength, elongation at break, and toughness value of the hydrogel are 2.5 MPa, 800%, and 1.1 MJ/m 3 . The lap shear adhesive performance test demonstrated that the hydrogel possesses excellent adhesion properties, capable of adhering to various substrates (with the highest adhesion strength observed on wood, reaching 76.8 kPa). Furthermore, the hydrogel can adhere to skin without leaving any residue upon removal. Results from in vitro coagulation tests revealed that the hydrogel fortified with TA effectively promotes blood coagulation on its surface. Antibacterial tests indicated that the TA‐containing organic hydrogel exhibits a significant inhibitory effect on Staphylococcus aureus . Additionally, TA can be gradually released from the hydrogel into a phosphate‐buffered saline (PBS) solution. Consequently, TA‐loaded hydrogels hold promising potential for application as wound dressings.","PeriodicalId":20281,"journal":{"name":"Polymer Engineering and Science","volume":"65 12","pages":"6890-6903"},"PeriodicalIF":0.0,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, PA6 nanocomposites were prepared via in situ ring‐opening polymerization using multi‐walled CNTs (MWCNTs) and polyvinylpyrrolidone (PVP) as a dispersant. By adjusting MWCNT content (0.1–0.5 wt.%) and PVP/CNT ratio, we elucidated the role of PVP in improving dispersion and interfacial compatibility. PVP enabled non‐covalent interactions (π‐π stacking and hydrogen bonding), leading to reduced CNT agglomeration and enhanced load transfer. Notably, the nanocomposite containing 0.3 wt.% MWCNTs and 0.3 wt.% PVP demonstrated the most balanced mechanical enhancement, achieving increases of 21.9% in tensile strength, 17.2% in tensile modulus, 15.8% in flexural strength, and 32.2% in impact strength compared to PA6. These improvements highlight the synergistic role of PVP in promoting nanotube dispersion and interfacial load transfer. Moreover, rheological analysis revealed a viscosity‐enhancing effect induced by the semi‐interconnected CNT‐PVP structure, which hindered molecular mobility and contributed to stress transfer across the interface. This work elucidates the molecular‐level mechanism of PVP‐assisted CNT dispersion in PA6 nanocomposites and highlights a scalable strategy for tailoring interfacial structures in CNT‐reinforced thermoplastics, offering valuable insights into the rational design of high‐performance nanocomposite systems.","PeriodicalId":20281,"journal":{"name":"Polymer Engineering and Science","volume":"66 1","pages":"122-139"},"PeriodicalIF":0.0,"publicationDate":"2025-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The covalent bonding link between the polypyrrole and the epoxidized natural rubber helps to establish an effective conductive network within the epoxidized natural rubber matrix. As a result, the strain sensor has a fast response (153 ms) and excellent cycling stability (over 2000 cycles at 40% strain). The gauge factor (GF) is 5.4 for strain below 100%, reaching 6845.6 for strain above 550%. In addition, A‐ENR‐g‐PPy‐based flexible strain sensors can accurately monitor and differentiate between small and large body movements such as finger, wrist, elbow, and knee bending as well as mouth opening and blinking.

The maximum thermal weight loss temperature of FTPE is 414.8°C under the synergistic action of the C–F bond. By changing the content of microcrystalline cellulose and acrylamide, the tensile strength of these fluorinated copolymers can be adjusted between 0.022 and 5.82 MPa, and their length can maintain a recovery rate of over 90% after multiple cycles. Meanwhile, owing to the soft rubber brushes in the side chains of MCC‐g‐P (AM‐ co ‐TFEA) and the strong cohesive force, the shear strength of the copolymer can reach 9.89 MPa when it is applied as a hot‐melt adhesive. This effective strategy can be further applied to improve the thermal and mechanical properties of bio‐based elastomer.

Since most conventional polymer microspheres and preformed gel particles have limitations in long‐term plugging of large pores and fractures, this study proposes a novel re‐crosslinkable calcium alginate (CaAlg) polymer microsphere system, which dynamically enhances the plugging performance by embedding glycerol triglycidyl ether (GTE). The microsphere triggers a ring‐opening addition reaction between GTE and polyethyleneimine (PEI) in the PEI solution, rapidly forming an integral gel, which significantly enhances both plugging strength and longevity of large pores and fractures. Re‐crosslinking time can be controlled by adjusting the injection timing of PEI to achieve dynamic optimization of plugging. Effects of temperature, PEI concentration, and salinity on microsphere re‐crosslinking behavior and gel mechanical properties were experimentally investigated. Size distribution, chemical structure, and micro‐morphology of the microspheres are characterized by laser particle size analyzer, infrared spectroscopy, and scanning electron microscopy (SEM). The re‐crosslinked gel achieves a plugging efficiency of up to 91% and reaches significantly higher plugging pressure compared to the original microspheres. The gel also effectively redirects fluid flow paths, thus expanding the swept range, which is proved by dye tracer experiments. The mechanism of re‐crosslinking and the principle of plugging are further revealed by molecular simulation and Zeta potential analysis. The microspheres have desirable injectability, salt tolerance, and plugging strength. Furthermore, the re‐crosslinking process is controllable, which means flexible operations during field application. As a result, this re‐crosslinkable microsphere system offers an efficient solution for plugging fractures in high‐salinity reservoirs and has broad applicability and significant engineering value.","PeriodicalId":20281,"journal":{"name":"Polymer Engineering and Science","volume":"65 11","pages":"6152-6168"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147912491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, the peel strength between the PP film and PA6 board bonded by the mixture of BOYPA and DGEBA could be obviously enhanced with the increase of BOYPA content due to the proper polarity and the formation of hydrogen bonds. Meanwhile, the impact strength of the mixture of BOYPA and DGEBA was significantly improved because of the good toughness of BOYPA.
