The polyaniline/gold (PANI/Au) have been successfully deposited on the surface of the poly(tetrafluoroethylent) (PTFE) membrane by one step process via simple diffusing interfacial reaction. The concentration ratio of aniline monomer to doping agent affected the microstructure and electrical conductivity of the composite membrane. The morphology and structure of the as-prepared composite membrane were characterized by using SEM, XRD, GIXRD, ATR-FTIR, Raman and UV–vis spectroscopy, and a difference on the upside and bottom side surfaces of the membrane was detected. As a candidate of advanced catalytic systems, the catalytic function of the Au on the surface of composite membrane was investigated and showed integrated benefits such as good catalysis, pollution-free, easy separation, convenient operation and regeneration in practical applications.
