초록

Elastic polypyrrole (PPy)/textile fabric composites with high electrical conductivity were prepared by coating PPy on an elastic nylon/spandex fabric through chemical and electrochemical oxidation of pyrrole in sequence. The electrical resistivity of the composite was extremely low as $0.2\;{\Omega}cm$ at fairly low PPy content. We investigated the effects of the preparation conditions on the properties of the resulting fabric such as PPy content, surface morphology and electrical conductivity. We also studied mechanoelectrical properties of the elastic fabric by measuring the change of electrical resistance during extension of the fabric, observing monotonic increase of the electrical resistance with the elongation. We suggest that electrically conducting elastic fabric can be used as a strain sensor for large deformation.
