Graphene　oxide　was　used　to　prepare　three　types　of　dye　modified　graphene　oxide　by　adsorbing　dyes　of　acid　blue　74,　methylene　blue,　and　congo　red.　The　as-prepared　dye　modified　graphene　oxide　was　used　to　fabricate　dye　modified　graphene　oxide/polyaniline　composites　via　an　in-situ　chemical　polymerization.　The　nanocomposites　were　labelled　as　acid　blue　74　modified　graphene　oxide/polyaniline　(GAP),　methylene　blue　modified　graphene　oxide/polyaniline　(GMP),　and　congo　red　modified　graphene　oxide/polyaniline　(GCP)　composites,　respectively.　Furthermore,　their　electrochemical　properties　as　electrode　materials　for　supercapacitor　were　studied.　The　results　demonstrate　that　polyaniline　(PANI)　nanorods　in　the　GAP　composite　are　20~30　nm　in　diameter　and　100~150　nm　in　length,　and　the　PANI　arrays　are　uniformly　and　orderly　constructed　in　the　composite;　whereas　the　PANI　nanorods　in　GMP　and　GCP　composites　possess　larger　size　in　diameter　and　length,　which　are　partly　aggregated　together.　The　specific　capacitances　of　GAP,　GMP,　and　GCP　are　up　to　419　F/g,　401　F/g,　and　399　F/g,　respectively,　at　a　current　density　of　0.5　A/g.　Comparing　with　the　specific　capacitance　of　PANI　(399　F/g),　these　composites　display　enhanced　specific　capacitances.　©,　2015,　Chengdu　University　of　Science　and　Technology.　All　right　reserved.
