Reduced graphene oxide (RGO)를 수용성 고분자인 poly(styrene sulfonate) (PSS)로 wrapping한 수분산성 그래핀 치환체인 G-PSS와 전도성 고분자인 poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate) (PEDOT/PSS)의 복합화에 관하여 연구하였다. G-PSS의 존재 하에서 PEDOT/PSS의 제자리 화학 중합 반응을 수행하여 복합체(GP)를 얻었다. 생성물의 XPS, IR 및 Raman 분석을 통하여 모노머인 EDOT의 중합이 원활하게 진행되어 PEDOT/PSS가 생성됨과 동시에 그래핀과 복합화되었다는 것을 확인할 수 있었다. 또한 GP는 $4.46{\times}10^2S/m$의 전도도를 나타냈으며, 0.5%의 농도까지 물에 분산이 되어 G-PSS보다 전기적 특성 및 수분산성 모두 우수하였다.
