摘要/Abstract

摘要：

为提高导电高聚物聚吡咯在涤纶长丝表面的黏附牢度,采用亚真空等离子体处理技术对涤纶表面进行改性处理,再通过原位聚合法制备聚吡咯/涤纶复合导电纱线,考察等离子体处理前后聚吡咯/涤纶复合导电纱线导电性能和耐久性变化。结果表明:利用亚真空等离子体处理产生的高能活性粒子在涤纶表面轰击产生微小凹坑,可有效增加涤纶表面粗糙度,但对涤纶力学性能无显著影响;该处理方式改善了聚吡咯薄膜的连续性、均匀度以及其与涤纶纱线基材的黏附牢度;复合导电纱线的导电性和耐久性均得到明显提高,等离子体处理前后复合导电纱线电导率分别为0.67 和1.16 S/cm。

Abstract:

In order to improve the surface adhesion fastness of the conductive polymer polypyrrole (PPy) on the polyester (PET) filament, the sub-vacuum plasma treatment technology was used for surface modification of polyester fiber, and the composite conductive PPy/PET yarns were prepared by in-situ polymerization method. The influence of plasma treatment on the electrical conductivity and durability of PPy/PET composite conductive yarns was investigated. The results show that the tiny concave pits appear on the surface of polyester fiber by the high-energy reactive particle bombardment of sub-vacuum plasma processing, which can effectively improve the surface roughness of the polyester fiber without significant influence on the mechanical properties of the substrate. The continuity and evenness of the PPy thin films was achieved by the sub-vacuum plasma treatment. The adhesion between PPy thin film and polyester yarns, the electrical conductivity and durability of composite conductive yarns were improved by the sub-vacuum plasma treatment. The electrical conductivity of composite conductive PPy/PET yarns before and after sub-vacuum plasma treatment is 0.67 and 1.16 S/cm, respectively.

Key words: sub-vacuum plasma, in-situ polymerization, composite conductive polypyrrole/polyester yarn, electrical conductivity, adhesion fastness
