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
