基于高强韧自修复聚氨酯的柔性应变传感器制备及其性能
Fabrication and properties of flexible strain sensor based on highly tough and self-healing polyurethane
摘要
Abstract
To address the performance failure issues due to fatigue or mechanical damage in flexible strain sensors during use,this study prepared a high-toughness,self-healing polyurethane based on a multi-hydrogen bond network.By compositing it with conductive antimony tin oxide(ATO)nanofibers,a highly stable,self-healing flexible strain sensor was developed and extensively characterized for its mechanical and sensing properties.Results indi-cate that the fabricated self-healing polyurethane exhibits a 900％elongation at break and a tensile strength of 8 MPa.The flexible strain sensor constructed from this polyurethane demonstrates a sensitivity as high as 240 with-in a strain range of 40％and maintains excellent cyclic stability.Additionally,thanks to the dynamic hydrogen bonding network of polyurethane,the sensor can fully recover its initial mechanical and sensing performance af-ter being damaged by heating.关键词
