However, there are limitations in the processing, mechanical, and barrier properties of these materials, which urgently need to be improved. The addition of additives is one of the most convenient and effective methods for obtaining high-performance polymer materials. However, there are few varieties of special modifiers for biodegradable materials, which are poorly targeted and have a single function, resulting in a small performance enhancement of biodegradable materials and high processing-and-moulding difficulties. In this study, in response to the characteristics of biodegradable materials (which generally have a low polymerization degree and require chain expansion during processing), epoxy functional additives (A-QR) with active components were successfully prepared using the ring-opening reaction between the hydroxyl and epoxy groups on quercetin. The results showed that the incorporation of A-QR improved the processing, thermal stability, crystalline, mechanical, and barrier properties of the films. In particular, when 0.6% A-QR was added to the PLA films, the tensile strength increased by 38.2%, and the water vapour transmission rate decreased by 18.9%. In addition, UV spectral analysis confirmed that A-QR conferred excellent UV shielding and antioxidant properties to the PLA films, with the UV shielding efficiency of the PLA/A-QR composite film reaching 79.24%, and the free radical scavenging rate increasing to 83%. Reactive extrusion technology enables effective immobilization of A-QR in PLA and limits its migration during use. The PLA/A-QR composite film demonstrated excellent freshness retention in food packaging applications.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 36","pages":"16530 - 16548"},"PeriodicalIF":3.9,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study develops a high-performance polyvinyl alcohol (PVA) hydrogel through dual-salt-regulation strategies involving sodium acetate (NaAc) and ammonium citrate (CAS). The in situ addition of NaAc (0.7 mol/L) induces PVA protonation, enhancing intramolecular/intermolecular hydrogen bonds (H-bonds), which elevates toughness to 1.3 MJ/m<sup>3</sup> (10 × improvement). Subsequent CAS salting-out (3 mol/L) further strengthens H-bond network and reduces crystalline domains, achieving exceptional mechanical properties: tensile stress (4.26 MPa), strain (760%), toughness (20.98 MJ/m<sup>3</sup>), and fracture energy (765.72 kJ/m<sup>2</sup>). Structural analyses confirm that NaAc disrupts PVA–water interactions, while CAS promotes dense chain packing via salting-out, collectively reducing water content from 88 to 26% and creating a hierarchical porous structure. Cyclic compression tests demonstrate outstanding fatigue resistance. The synergistic Hofmeister effect and dynamic ionic cross-linking enable energy dissipation, making this hydrogel promising for soft robotics and biomedical applications requiring robust, deformable materials.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 36","pages":"16559 - 16575"},"PeriodicalIF":3.9,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145090573","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a series of mesoporous carbon gels (CGs) with tunable pore size were synthesized and evaluated for their application as EDLC electrode materials. The advantages of the mesoporous structure in promoting ion diffusion and enhancing rate performance were verified by comparing with conventional microporous activated carbon (AC). While micropores (< 2 nm) are known to deliver high capacitance in aqueous and organic electrolytes, their accessibility in viscous ionic liquids is limited, thereby reducing power performance. Experimental results show that materials such as carbon gel synthesized at pH 5.9 and activated with CO<sub>2</sub> (denoted as CG59-CO<sub>2</sub>) achieve energy densities as high as 180 Wh/kg at a voltage window of 4 V, which is comparable to the energy density of lithium-ion batteries that are widely used today.
