Abstract Poly(N-methylaniline) (PNMA) has been electropolymerized for the first time from a graphene oxide (GO) dispersion containing 1.0 M HClO4. Both \{GO\} and perchlorate were incorporated in the \{PNMA\} matrix during the electropolymerization resulting in the formation of a mixed composite material of PNMA-ClO4 and PNMA-GO. Under the acidic polymerization conditions, the carboxylic groups of \{GO\} are undissociated and \{GO\} is therefore mostly mechanically entrapped in the \{PNMA\} matrix while perchlorate functions as the primary charge compensating ion. Electrochemical reduction at −0.85 V improved the electron transfer of the composite film due to reduction of \{GO\} in the \{PNMA\} matrix.
