The electrical conductivity of polyphenylacetylene (PPA) was enhaced by eleven orders of magnitude after absorption of bromine vapor. TG, UV-Vis spectra, and XPS spectra were used to study the interaction among bromine, nano-graphite and PPA. According to the results, bromine played a major role to enhance the conductivity of the composites when the weight percentage of bromine doped graphite was low. When the weight percentage of bromine doped graphite was high, the doping effect formed by bromine doped nanographite and bromine doped PPA, was the main point to enhance the conductivity. When the weight percentage of bromine doped nano-graphite was higher, the conductive network formed by bromine doped nano-graphite, played a major role.
