Surface Interactions: Functionalization of Graphene Oxide and Wetting of Graphene Oxide and Graphene

Surface interactions of graphene oxide (GO) and graphene are presented in this review. This work is intended to complement previous reviews of graphene oxide chemistry as well as detail the newest efforts in this growing field. GO holds great promise as both a starting material for 2-D materials and as a platform for chemical reactions, and in both cases potential applications for these materials continue to increase. This work seeks to highlight reactions that promote attachment of different moieties and that "tune" the surface energies of GO that may enhance local interactions. Keywords: Functionalization, graphene, graphene oxide, nanoparticles, transparency, wetting.
