Real-time deformation monitoring during service can provide timely performance assessments, accurately evaluate damage, reduce maintenance costs, and enhance construction efficiency. Conductive elastomers, which exhibit a resistance/strain response, are effective sensing materials for such monitoring. However, they often suffer from a shoulder peak effect in their output monitoring signals, compromising monitoring stability and reliability. In this study, we endowed elastomer (VMQ) with conductive properties using multi-walled carbon nanotubes (MWCNT) and modified its cross-linking structure with Hydrogen silicone oil (TMS) and Hydrosilane (HSO) to eliminate the shoulder peak effect. Results showed that introducing dihydrogen structures reduced the resistive hysteresis area by 94.22 % and eliminated the shoulder peak effect. The underlying mechanism was explored through a combination of experiments and molecular dynamics (MD) simulations. Additionally, the tensile strength and elongation at the break of the conductive elastomer improved by 21.89 % and 45.11 %, respectively. The optimized conductive elastomer exhibited excellent strain-sensing properties, including high sensitivity (GF = 2918.524) and a fast response time (217 ms). Its resistance/strain response remained stable and free of shoulder peak effects across different strain levels and strain rates after 5000 loading-unloading cycles. When applied to seismic isolation bearings, the material maintained a stable monitoring signal under large deformations. These findings highlight the potential of this innovative sensing composite for structural health monitoring in large-scale components.</div></div>","PeriodicalId":17219,"journal":{"name":"Journal of Science: Advanced Materials and Devices","volume":"10 3","pages":"Article 100924"},"PeriodicalIF":6.7,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144321780","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, MIL-125(Ti)–NH₂ is used during an interfacial polymerization reaction for fabricating titanium-based thin film nanocomposite (TFN) FO membrane.

The results show a significant reduction in contact angles (up to 33 %) and an increase in surface roughness (by approximately 31 %) after the monomer polymerization reaction, indicating that the formation of a selective layer resulted in higher hydrophilicity of the TFC/TFN membranes as well as good compatibility between polymer and fillers. Furthermore, the addition of titanium-based fillers improved FO membrane water flux by 240 % and lowered the specific reverse salt flux due to the non-covalent bond among water molecules and the –NH₂ group.

Hence, this work was focused on obtaining nano-sized silver phosphate and then purposely decorating the amine (-NH₂) functional groups on the AgP NPs, resulting in F–AgP.
