Graphene-based composites

Abstract

Graphene has attracted tremendous research interest in recent years, owing to its

exceptional properties. The scaled-up and reliable production of graphene derivatives,

such as graphene oxide (GO) and reduced graphene oxide (rGO), offers a wide range of

possibilities to synthesize graphene-based functional materials for various applications.

This critical review presents and discusses the current development of graphene-based

composites. After introduction of the synthesis methods for graphene and its derivatives

as well as their properties, we focus on the description of various methods to synthesize

graphene-based composites, especially those with functional polymers and inorganic

nanostructures. Particular emphasis is placed on strategies for the optimization of

composite properties. Lastly, the advantages of graphene-based composites in

applications such as the Li-ion batteries, supercapacitors, fuel cells, photovoltaic devices,

photocatalysis, as well as Raman enhancement are described.
