The conducting composites were prepared by emulsion polymerization with poly (acrylonitrile-co-butadiene) (NBR) as a matrix and polypyrrole (PPY) as a conducting polymer. Among several surfactants, the electrical conductivity of the composite which was polymerized by dodecyl sodium sulfate (DSS) was the best. The film of composite was prepared by compression molding. The electrical conductivity was measured by 4 probes method as a function of PPY and temperature. When the content of PPY was 25 wt%, the electrical conductivity of composite was increased up to 1.17 S/㎝. The percolation threshold showed at the vicinity of 15 wt% PPY content.
