PHOTOSWITCHABLE GRAPHENE MEMBRANES

摘要

Graphene composites are disclosed. The graphene composites may include, for example, a photoswitchable layer, a graphene layer, and a substrate. The graphene composites may, in some embodiments, include a graphene layer with photoswitchable surface characteristics. Methods of making the graphene composite are further disclosed. Devices and systems configured to make and use the composites are also disclosed.
