Novel antistatic polyaniline/poly(vinyl chloride) (PVC) composite materials are prepared. This study focuses on modification of PVC matrix with different content of polyaniline nanorods. Polyaniline nanorods can reduce the volumn resistivity of PVC/polyaniline composites 1016 Ω cm from to 1011 Ω cm five orders of magnitude at low content of 2 wt %. Moreover, the mechanical performance of the composite material is also good. Based on the results, we have confidence in the new antistatic composites.
