Abstract

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.

通过在 "骨架-毛细管 "碳纳米管网络中原位形成纳米多孔石墨烯构建柔性全碳纳米体系结构，用于超级电容器。

碳质材料很难将大比表面积与柔性结合起来。在这里，我们通过化学气相沉积（CVD）工艺，在 "骨架-毛细管 "碳纳米管（CNT）网络中原位生长出了纳米多孔石墨烯，并在此基础上实现了柔性全碳纳米结构。多孔石墨烯为电荷存储提供了较大的比表面积。薄膜的柔韧性使其可以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合剂，超级电容器显示出更高的整体存储密度。

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
