石墨烯/偶氮杂化材料研究进展
摘要
Graphene, a true two dimensional nanomaterial with the layer thickness of one atom, has showed many outstanding properties and aroused tremendous research enthusiasm. Azobenzene-containing polymers and other materials have also attracted considerable attention because of the unique photoresponsive properties. Graphene/ azobenzene hybrids materials can combine interesting properties of graphere and azobenzene-containing materials and have been studied in authors and other laboratories in recent years. This review highlighted some recent research progresses in this area. The content of this article included the preparations of graphene/azobenzene hybrids materials through surface-grafting of azo polymers, covalent-bonding modification with low-molecular-weight azo compounds and electrostatic layer-by-layer deposition. The photoresponsive properties and application in the electronchemical energy storage device of the materials were also reviewed in some detail.
