摘要
Thin multilayer graphene/PEDOT films were prepared by electrochemical deposition. PEDOT was deposited on gold electrodes by cyclic voltammetry, and p-doped graphene, which was synthesised from expanded and p-doped graphite, was assembled on the PEDOT-coated electrode by chronoamperometry at -1 V. The process was repeated as necessary to obtain the desired number of multilayers. Successful deposition of graphene/PEDOT layers was demonstrated by SEM. The maximum specific capacitance of the multilayer film was 154 F g(-1) for six graphene layers. Further, the multilayer film exhibited improved electrochemical stability with a retention life of 86% after 1000 cycles.
