In this study, novel liquid-free ICEs are conveniently fabricated through the complexation of 4-carboxybenzaldehyde-grafted poly(vinyl alcohol) (CPVA) with well-designed solid quaternary ammonium (QA) molecules bearing bifunctional hydrogen-bonding moieties. The resulting CPVA-QA elastomers, which are highly elastic and adhesive to diverse surfaces, exhibit a tensile strength of 6.6 MPa, a toughness of 14.7 MJ m⁻³, and a Young’s modulus of 0.15 MPa. These elastomers have a hydrogen-bonded network structure where the bifunctional QA molecules significantly suppress polymer chain entanglements. Benefitting from the thermally sensitive hydrogen bonds and the substantially reduced chain entanglements, the CPVA-QA elastomers show a high chain mobility upon temperature elevation, which facilitates ion transport within the CPVA-QA elastomers. Consequently, the CPVA-QA elastomer-based temperature sensors show an outstanding temperature resolution (0.05 °C), a fast response time over a wide temperature range, and a record-high thermosensitivity of 10.8% K⁻¹. Importantly, the CPVA-QA sensors can be depolymerized under mild conditions to recover their original components in high purity and yields (&gt;96%), enabling closed-loop recycling of the sensors.</p>","PeriodicalId":9810,"journal":{"name":"CCS Chemistry","volume":"126 1","pages":""},"PeriodicalIF":11.2,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142556296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
