Abstract
AbstractWe could prepare highly electrically conducting graphitic carbon films and nano patterns by carbonizing the poly(p‐phenylenevinylene) (PPV) films and nano patterns prepared on the silicon surface by the chemical vapor deposition polymerization method of α,α'‐dichloro‐p‐xylene. When the PPV films on silicon wafers were thermally treated at 850°C highly oriented graphitic carbon films were obtained which exhibit an electrical conductivity higher than 0.7 x 103 Scm−1. This conductivity value is more than 10 times the value for the carbon films obtained from bulk PPV films or glassy carbons heat treated at the same temperature. Moreover, nano patterns of graphitic carbons were easily obtained on silicon wafers through carbonization of nano patterned PPV obtained by the CVD polymerization method.
