AbstractAn insulating silicon-containing polyimide (SiDA-BDA), derived from polycondensation of bis(3,4-dicarboxyphenyl)dimethylsilane dianhydride and benzidine, was converted into a conducting material after pyrolysis at 800-1000 degreesC in a nitrogen atmosphere. The maximum room temperature conductivity (sigma(RT)) of about 68 S cm(-1) was obtained for SiDA-BDA film pyrolyzed at 1000 degreesC for 1 h. X-ray photoelectron spectroscopy (XPS) studies showed that the nitrogen atoms tended to evaporate quickly at pyrolysis temperature (T,) higher than 800 degreesC while the silicon atoms tended to form silicon carbides and silicon oxycarbides as the pyrolysis temperature increased. The conducting behavior of the pyrolyzed SiDA-BDA films is in some ways typical of semiconductors while in other ways it is typical of conductors and can be described by a modified Mott's 3D variable-range hopping (3D VRH) model.
