Composite material, method of manufacturing same, electrode applied with composite material and method of manufacturing same

The invention provides a composite material, a method of manufacturing the same, an electrode applied with the composite material and a method of manufacturing the same. The method of manufacturing acomposite material comprises first, providing graphene oxide and activated carbon; uniformly dispersing the graphene oxide and the activated carbon into an alcohol to form a mixture; and heating the mixture by microwave in a single step, to uniformly reduce the graphene oxide to graphene at active sites of a surface of the activated carbon, thereby forming the composite material. The embodied composite material is suitable for being the electrodes of the capacitive deionization (CDI) and supercapacitor application. 本发明提供种复合材料与其制造方法以及应用复合材料的电极及其制造方法，所述复合材料制造方法，包括：提供氧化石墨烯和活性炭；将所述氧化石墨烯和所述活性炭均匀分散于醇类中，以形成混合物；以及对所述混合物进行单步骤的微波加热，以均匀地将所述氧化石墨烯还原于所述活性炭的表面活性位置上，而形成复合材料。实施例的复合材料也适合应用于电容脱盐(CDI)及超级电容(supercapacitor)的电极制作。
