▎ 摘　　要

Recent achievements in the construction of graphene-based materials with superwetting properties have been developed and received significant research attention. Deeply understanding and effectively con-trolling the wettability of graphene-based materials is crucial for its fundamental research and functional application. Therefore, in this review, after a brief introduction to the intrinsic wettability of graphene and graphene oxide (GO). The strategies for manipulating the wettability of graphene-based materials to achieve superwetability are summarized and discussed, including chemical composition regulation and multiscale structure construction. Then, we also propose a framework for the promising applications of graphene-based superwetting materials in oil-water separation, droplet manipulation, self-cleaning coatings and energy-related applications. Finally, we provide our views and recommendations on the challenges and future research directions in this emerging and promising research field. (c) 2023 Elsevier Ltd. All rights reserved.
