摘要:采用低温原位聚合法在尼龙织物表面形成一层聚苯胺导电材料,并用场发射扫描电子显微镜和显微拉曼
成像光谱仪对其形貌及化学组成进行了表征,用数显万用表和电化学工作站测试了其导电性能。结果表明,聚
苯胺聚合在尼龙织物的表面,赋予尼龙织物较好的导电性,聚苯胺尼龙导电织物电导率为 31.62 S/m。聚苯胺尼
龙导电织物的电阻随应变的增大而增大,当应变回复到初始状态时,电阻逐渐恢复并接近初始值,在 3500 次拉
伸-回复循环后仍有 96.2%的高循环稳定性。聚苯胺尼龙导电织物具有良好的传感性能,在 0~15%应变范围内可
以准确监测人体的关节运动。同时,聚苯胺尼龙导电织物也具有热电性能,其塞贝克系数为 8.406 μV/K,有望
作为温差传感器。

Abstract: A layer of polyaniline conductive material was developed on the surface of nylon fabric by low
temperature in situ polymerization, and characterized by field emission scanning electron microscopy and
microscopic Raman imaging spectrometer for morphology and chemical composition analyses. The
conductivity of polyaniline nylon fabric was then measured by digital multimeter and electrochemical
workstation. The results showed that polyaniline polymerized on the surface led to the improvement of
electrical conductivity, 31.62 S/m, of polyaniline nylon conductive fabric. The resistance of polyaniline
nylon conductive fabric increased with the increase of strain, but gradually recovered back to the initial
value when the strain returned to the initial state. The polyaniline nylon conductive fabric still maintained a
high recycle stability of 96.2% after 3500 stretching-releasing cycles. Furthermore, the polyaniline nylon
conductive fabric exhibited good sensing performance and could accurately monitor the joint movement of
human body within strain ranging from 0 to 15%. Meanwhile, the polyaniline nylon conductive fabric
displayed thermoelectric properties. With a Seebeck coefficient of 8.406 μV/K, the fabric showed good
potential in temperature sensing.
