摘　　要：以原位化学沉积法制备了聚吡咯织物基压力传感材料,通过改变纤维材质和织物组织,获得具有不同性能的传感材料。观察了其微观形貌,测试了力学性能和传感性能,用以研究纤维材质和织物组织对压力传感性能的影响。结果表明:芳纶平纹组织织物表现出更高的灵敏度,低压力区(0~25 k Pa)灵敏度高达5.094 k Pa^(-1),施加应力和撤除应力的响应时间分别为100 ms和250 ms,同时表现出优异的循环稳定性。Polypyrrole fabric-based pressure sensing materials are prepared by in-situ polymerization.The sensing materials with different properties are obtained by changing the fiber material and fabric texture.The microscopic morphology is observed,and mechanical properties and sensing properties are tested to study the influence of fiber materials and fabric texture on pressure sensing performance.The results indicate that the plain weave fabric woven with aramid exhibits higher sensitivity.The sensitivity in the low-pressure region(0~25 k Pa)reaches as high as 5.094 k Pa.The optimized sensor also presents fast response(100 ms and 250 ms when the pressure is loaded and removed)and excellent cycling stability.
