Surface Treatment of Three-Dimensional Graphene Oxide Using Ultraviolet Radiation

Graphene is one of the most popular carbon structures used in biology. If surface treatments are applied on this material, its applications increases significantly. The aim of this study was to investigate the effect of surface modification on graphene hydrophilicity using ultraviolet (UV) radiation. In this study, the value of hydrophilicity of two graphene groups, with and without surface treatment, was investigated by passing an aqueous solution through the groups in 48 hour periods. In addition, seeking the reason behind different amounts of aqueous solution passed through the two group samples, surface functional groups were characterized using Fourier Transform Infrared spectroscopy (FTIR). The results show that the treatment of surface functional groups by UV radiation has a remarkable effect on surface hydrophilicity
