To overcome these challenges, this study developed a sericin-MXene/phenylboronic acid-polyacrylamide (PADS-MXene) composite hydrogel by copolymerizing 3-acrylamidophenylboronic acid with acrylamide and incorporating polydopamine-modified sericin-functionalized MXene. In this system, the polydopamine-modified sericin (PDA-SS) not only expanded the interlayer spacing of MXene and prevented nanosheet aggregation but also introduced polar functional groups, strengthening hydrogen bonding between MXene and the polyacrylamide network. The resulting hydrogel exhibits excellent mechanical properties, with a fracture strength of 60 kPa and a fracture strain of 380%, coupled with low hysteresis (1.65% after 30 cycles), and efficient self-healing ability. MXene also enhances its high electrical conductivity and photothermal response, enabling rapid 20°C within 300 s under near-infrared light. Functioning as a wearable strain sensor, the hydrogel can reliably monitor movements across various parts of the human body and maintain stable performance even after 2000 cycles at 50% strain. It also enables handwriting posture correction via pressure distribution and Morse code messaging via short/long presses for emergency communication. These features highlight its potential for durable, multifunctional flexible sensing systems.</p>\u0000 </div>","PeriodicalId":16888,"journal":{"name":"Journal of Polymer Science","volume":"64 17","pages":"3743-3758"},"PeriodicalIF":3.9,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148862409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four GECO elastomers with different monomer compositions, molecular weights, and branching architectures were compounded with varying amounts of novolac-type phenolic resin. Cure kinetics were evaluated by moving die rheometry (MDR), while network structure and viscoelastic behavior were characterized using rubber process analysis (RPA), temperature-scanning stress relaxation (TSSR), cyclic compression, rebound resilience, and dynamic mechanical analysis. Increasing PR content reduced torque and crosslink density, producing softer networks and enhanced energy dissipation, as evidenced by higher tan δ values, greater hysteresis losses, and lower rebound resilience. Correlation analysis demonstrated that elastic recovery is primarily governed by network density, whereas damping behavior is additionally influenced by polymer architecture. Among the investigated materials, T3108 exhibited a more elastic response, while T3100 showed a more dissipative viscoelastic character.
