PEDOT∶PSS基材料在柔性传感与监测器件中的应用研究OA

Conductive polymer poly(3,4-ethylenedioxythiophene)∶poly(styrenesulfonate)(PEDOT:PSS)has become an ideal material for flexible sensing and monitoring due to its high conductivity,flexibility,and solution processability.The article systematically summarized its application progress in related fields and analyzed the structure-property relationships and performance optimization strategies.The applications of PEDOT∶PSS in three major fields-chemo/biosensing,pressure monitoring,and strain sensing-were comprehensively discussed,with an analysis of how molecular engineering,structural design,and composite material synergy addressed core issues such as stability,sensitivity,and mechanical compatibility.The study showed that in chemical sensing,anchoring active materials to conductive scaffolds enabled highly sensitive and stable detection.In pressure monitoring,microstructural design and compositing with functional materials balanced a wide detection range with high sensitivity,and intelligent interaction was achieved through integration with machine learning.In strain sensing,interfacial engineering and multi-level structural regulation synergistically enhanced mechanical toughness and electrical response speed.With its multi-level tunability,PEDOT∶PSS served as a bridge connecting fundamental research and practical application.
