摘要：

为改善聚吡咯复合织物的导电性和疏水性,采用不同软模板制备聚吡咯复合棉及涤纶织物。借助扫描电子显微镜对聚吡咯复合材料的微观形貌进行表征,测试了聚吡咯/棉织物和聚吡咯/涤纶织物的表面电阻、电导率、接触角、K/S值、干摩擦等级以及断裂强力等性能变化。结果表明:制备聚吡咯/棉织物和聚吡咯/涤纶织物电导率最高的软模板均为蒽醌-2-磺酸钠盐,聚吡咯/棉织物电导率较大;棉织物以甲基橙为软模板,涤纶织物以木质素磺酸钠为软模板时疏水效果最好;棉织物以十二烷基苯磺酸钠和十六烷基三甲基溴化铵为软模板时耐摩擦等级效果最好,聚吡咯/涤纶织物的干摩擦等级均很低,需要进一步提高其耐摩擦性能。

Abstract:

In order to improve conductivity and hydrophobicity of polypyrrole composite fibers, polypyrrole composite cotton and polyester(PET) fabrics were prepared by different soft templates. The micro-morphology of the composite material were characterized by scanning electron microscopy, and the surface resistance, electrical conductivity, contact angle, K/S value, dry friction and breaking strength of the polypyrrole/cotton and polypyrrole/polyester fabrics were tested. The results show that the best soft template for polypyrrole/cotton fabric and polypyrrole/polyester fabric is sodium anthraquinone-2-sulfonate, considering the highest conductivity, polypyrrole/cotton fabric has higher conductivity. Hydrophobic effect is the best when methyl orange is used as soft template for cotton fabric, and for polyester fabric sodium ligninsul-fonate(LGS) is used as soft template. The friction grade is the best when the LGS is used as the soft template for cotton fabric. For polypyrrole/PET fabric, the friction grade is lower except sodium dodecyl benzene sulfonate and hexadecyl trimethyl ammonium bromide as the soft temperature, and the abrasion resistance is needed to be further improved.

Key words: polypyrrole, soft template, conductivity, contact angle, conductive property, hydrophobic property, polyester fabric, cotton fabric
