THREE-DIMENSIONAL GRAPHENE-BASED HYDROGEL/AEROGEL MATERIALS

Abstract

Graphene-based hydrogels/aerogels (GHA) have attracted widespread attention due to its excellent mechanical strength, electrical conductivity, thermal stability and adsorption capa- bility. In this article, some research achievements are reviewed on preparation strategies, forma- tion mechanisms and potential applications of GHA. Except for the normal method of self-as- sembly, some new technologies for fabricating GHA framework were summarized including chemical reduction self-assembly, polymerization, adding cross-linking agents and so on. Mean- while, we concluded the applications in various fields, such as environmental protection, bio- medicine and energy sources. Finally, a perspective in the future challenge about fabricating GHA is also given.
