The associated safety issues can be effectively addressed by employing gel polymer electrolytes (GPEs). Although traditional polyethylene oxide (PEO) based GPE exhibits good compatibility with lithium anodes, its lower oxidative decomposition potential (< 4 V) restricts its application in 4.2 V LMBs. To extend the oxidative stability of PEO, we propose a PEO blended GPE that incorporates the water-soluble zwitterionic polymer, poly(sulfobetaine methacrylate) (PSBMA), synthesized <em>via</em> free-radical polymerization. The blended polymer membrane was fabricated using electrospinning with water as the solvent. The environmentally friendly membrane with porous fiber structure shows the increased ionic conductivity of 1.8 × 10<sup>‐3</sup> S cm<sup>‐1</sup> for PPA25-GPE (PEO: PSBMA = 75 %: 25 %), compared to 1.0 × 10<sup>‐3</sup> S cm<sup>‐1</sup> for PEO based GPE. Furthermore, the oxidative potential of PPA25-GPE is extended to 5 V <em>vs</em> Li/Li<sup>+</sup>. The superior film-forming ability and wettability properties of PSBMA, attributed to its zwitterionic groups, improve the interfacial compatibility between GPE and electrodes, contributing to the cyclic performance of the assembled battery.

The coating combines low-surface-energy dodecyl trimethoxysilane (DTMS) with pH-sensitive 3-aminopropyl triethoxysilane (KH550) modified SiO<sub>2</sub> nanoparticles. The coating's structure, morphology, and properties were characterized using Fourier transform infrared (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), and water contact angle measurements (WCA). Compared to existing pH-responsive systems, this coating exhibits superior switching speed: it transitions rapidly from superhydrophobicity (WCA > 150° at pH 7) to superhydrophilicity (WCA decreases from 50.24° to 0° within 20 s at pH 1) and reversibly back to superhydrophobicity (WCA = 163° at pH 13). The coating demonstrates excellent stability in various salt solutions (NaCl, KCl, KNO<sub>3</sub>) and under ultrasonic washing, ensuring robustness in complex aqueous environments. Leveraging this reversible wettability switching, the coating achieves high separation efficiencies for both high-density (98.5 %) and low-density (96 %) oil/water mixtures. Critically, this fabrication strategy eliminates the need for expensive, environmentally hazardous heavy metals (e.g., Ag, Au, Cu) or complex polymerization processes commonly employed in other smart separation materials. The combination of rapid switching, environmental and economic friendliness, salt resistance, durability, and high separation performance underscores the significant potential of this coating for diverse practical oil/water separation applications.</div></div>","PeriodicalId":20916,"journal":{"name":"Reactive & Functional Polymers","volume":"217 ","pages":"Article 106498"},"PeriodicalIF":5.1,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
