Outline of Final Research Achievements

The effect of graphene oxide (GO) content and heat treatment temperature on the conductivity of the composites from conductive polymers such as poly(aniline)(PANI) doped with dodecylbenzene sulfonic acid (DBSA), poly(aniline sulfonic acid) and poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(stylene sulfonic acid) (PSS) and GO was studied. It was found that the moderate ratio of above conductive polymer to GO and higher heat treatment temperature than 150℃ enhanced the conductivity of the composites such as PANI:DBSA/GO, PAS/GO and PEDOT:PSS/GO. It was made clear that such conductivity enhancement resulted from the increase of C(sp2) bonds due to O-removal reaction of GO, which was promoted by sulfonic acid group (SO3H) as a dopant.
