Polydopamine modified reduced graphene oxides (PDA‐rGO) are synthesized by a facile dopamine polymerization reaction. As‐prepared PDA‐rGO shows a capable electrochemical performance as an electrode material for supercapacitors. A capacitance of 120 F g⁻¹ is achieved at current density of 2 A g⁻¹. PDA‐rGO also presents a superior cycling performance with capacitance retention of ∼99% after 10000 cycles. The remarkable electrochemical performance is attributed to the addition of PDA, which prevents the stacking of rGO and enhances the wettability of composite. Meanwhile, the rGO with high conductivity promise fast electronic transport.

聚多巴胺改性的还原石墨烯氧化物可作为高性能超级电容器的电极

聚多巴胺改性的还原石墨烯氧化物（PDA-rGO）是通过简单的多巴胺聚合反应合成的。制备的PDA-rGO作为超级电容器的电极材料显示出强大的电化学性能。在2 A g ^-1的电流密度下可获得120 F g ^-1的电容。PDA-rGO还具有出色的循环性能，在10000次循环后的电容保持率约为99％。出色的电化学性能归因于PDA的添加，它防止了rGO的堆积并增强了复合材料的润湿性。同时，具有高电导率的rGO保证了快速的电子传输。
