▎ 摘　　要

It is shown that electrochemical characteristics of electrochemically synthesized composite materials (CMs) based on reduced graphene oxide nanosheets (RGONS) and polyaniline (PAni) depend considerably on the composition of CMs. Drastic variation of specific electrochemical capacity C (s) in CMs is observed in the range of PAni content of 30-75 wt %. In the same range of compositions, practically full RGONS surface coverage by the synthesized PAni is observed, as shown by SEM.
