通过简便的模板方法制备了具有分级结构的高柔性石墨烯自支撑薄膜。该薄膜具有多孔结构，可以轻松弯曲和切割，并与另一种材料作为支架形成复合材料。 3D石墨烯薄膜表现出优异的倍率性能，并且通过与聚苯胺纳米线阵列形成复合材料进一步提高了其电容。柔性分级复合材料被证明是柔性超级电容器的优异电极材料。
A highly flexible graphene free-standing film with hierarchical structure is prepared by a facile template method. With a porous structure, the film can be easily bent and cut, and forms a composite with another material as a scaffold. The 3D graphene film exhibits excellent rate capability and its capacitance is further improved by forming a composite with polyaniline nanowire arrays. The flexible hierarchical composite proves to be an excellent electrode material for flexible supercapacitors.
