It is difficult for carbonaceous materials to combine a large specific surface area with flexibility. Here, a flexible all-carbon nanoarchitecture based on the in situ growth of nanoporous graphene within "skeletal-capillary" carbon nanotube (CNT) networks has been achieved by a chemical vapor deposition (CVD) process. Multi-path long-range conductivity is established, and the porous graphene provides a large specific surface area for charge storage. The flexibility of the films allows them to be directly used as binder-free electrodes for supercapacitors. Since the polymeric binders are saved, the supercapacitors exhibit a higher overall storage density.
含碳材料很难兼具大比表面积和柔韧性。在此，通过化学气相沉积（CVD）工艺，在“骨架-毛细管”碳纳米管（CNT）网络中原位生长纳米多孔石墨烯，实现了一种柔性全碳纳米结构。建立了多路径远程导电性，多孔石墨烯为电荷存储提供了大比表面积。薄膜的柔韧性使其能够直接用作超级电容器的无粘结剂电极。由于省去了聚合物粘结剂，超级电容器展现出更高的整体存储密度。
