摘要：

Stable dispersions of graphene oxide (GO) and reduced GO (rGO) in different solvents were prepared. Specific features of their optical characteristics were studied by UV-spectroscopy. A method is proposed for the reduction of GO as component of coatings deposited on single-crystalline potassium dihydrogen phosphate (KDP) substrates by the reactions with various reducing agents including hydrazine monohydrate, aqueous formaldehyde solution, ascorbic acid, and citric acid. The surface structures were studied by Raman spectroscopy. The surface morphology of the coatings and structure imperfection of the graphene-like materials obtained by applying the GO and rGO dispersions onto the KDP surface were studied.
