Abstract：Polypyrrole/graphitic carbon nitride composites were synthesized via in situ polymerization. The conductive/electrochemical properties of polypyrrole/graphitic carbon nitride composites with different ratios of PPy to gC3N4 were investigated. Scanning electromicroscopy (SEM), transmission electron microscopy(TEM), Xray diffraction and fourier transform infrared spectroscopy(FTIR) were used to determine morphology and structure of the composite materials (PPy/gC3N4). The results indicate that the PPy particles are deposited on the surface of gC3N4, and a small amount of PPy particles are intercalated in the interlayer of gC3N4. The conductive and electrochemical properties of PPy/gC3N4 composites were investigated by fourprobe and cyclic voltammetry. The conductivity of the composites rises first with latter decreasing, and reaches the maximum value for gC3N4 content of 15%. The cyclic voltammetry test presents that the composites possess excellent redox reversibility. The specific capacitance of PPy/ gC3N4 composites increases with the increasing of gC3N4 content.
