一种PEDOT:PSS包覆纳米MnO2的石墨烯纳米墙电极制作方法
摘要：
本发明公开了一种PEDOT:PSS包覆纳米MnO2颗粒的石墨烯纳米墙电极制作方法，包括如下步骤：1)制备石墨烯纳米墙；2)对石墨烯纳米墙表面进行改性；3)石墨烯纳米墙上沉积PEDOT:PSS/MnO2薄膜；4)将载有PEDOT:PSS/MnO2薄膜的石墨烯墙/基底置于氮气环境中于100‑400℃热处理。采用本发明的方法制备的超级电容器电极通过PEDOT:PSS导电聚合物增强了石墨烯墙的导电性并作为保护层减少了电解液对MnO2的腐蚀，通过石墨烯纳米墙和PEDOT:PSS包覆MnO2纳米颗粒实现同时具有双电层和赝电容特性的电极，和传统石墨烯墙相比提升数十倍，且工艺过程简单，成本低廉，可大规模生产。
摘要（英）：

The invention discloses a fabrication method of a PEDOT:PSS-coated nano MnO<2> particle-based graphene nano wall electrode. The method comprises the following steps: (1) preparing a graphene nano wall; (2) carrying out modification on the surface of the graphene nano wall; (3) depositing a PEDOT:PSS/MnO<2> thin film on the graphene nano wall; and (4) carrying out heat treatment on a PEDOT:PSS/MnO<2> thin film-loaded graphene wall/substrate in a nitrogen environment at 100-400 DEG C. According to the super capacitor electrode prepared by the method disclosed by the invention, the conductivity of the graphene wall is enhanced through a PEDOT:PSS conductive polymer; corrosion to MnO<2> caused by an electrolyte is reduced by the super capacitor electrode as a protection layer; the electrode with electric double layers and pseudocapacitance characteristic is achieved through the graphene nano wall and PEDOT:PSS-coated MnO<2> nano-particles; compared with a traditional graphene wall, the specific capacitance is improved by more than 10 times; and the graphene nano wall electrode is simple in technological process and low in cost, and can be produced on a large scale.
