摘要
为制备超高分子量聚乙烯/聚苯胺复合导电纱线,以超高分子量聚乙烯长丝纱为基材,对其采用常压等离子体预处理后,进行基于原位聚合的纱线连续导电处理。利用制得的复合导电纱线制备了圆筒状纬平针织物作为应变传感器,研究了传感织物的应变-电阻传感性能。结果表明:导电针织物表现出明显的应变-电阻传感性能,其电阻随应变的增大先增大,至一定值后随着应变的增大而减小;传感织物具有较高的敏感度,在应变小于20%时,其传感因子可达30以上;多次拉伸时,传感织物的传感重复性逐渐提高,拉伸3次以后,传感织物表现出良好的传感重复性。
After pretreatment by atmospheric pressure plasma is carried out, ultrahigh molecular weight polyethylene （UHMWPE） filament yarn was used as the base material to fabricate the conductive UHMWPE/polyaniline （PANI） composite yarn continuously by a novel method based on in-situ polymerization in this paper. A cylindrical plain weft knitted fabric was fabricated from the conductive UHMWPE/PANI composite yarn, and its strain-resistance performance was studied. The results indicated that the resistance of sensing fabric increased first with increasing the strain and then decreased. The sensing fabric showed great sensitivity and the gauge factor was more than 30 when the strain was less than 20%. The repeatability of sensing fabric enhanced with the stretching time and it showed good repeatability after repeated stretching for 3 times.
