The study of amount of graphene when used as nano sheets in polymer matrices to form advance multifunctional material is one of the most promising research field. The effect of graphene on the desalination properties of epoxy coating has been evaluated by incorporating different concentration. In this study, the effect of graphene on the desalination properties of epoxy nano composites has been evaluated by incorporating concentration of nano particles i.e. 0.75% and 1.5% weight of graphene into epoxy polymer matrix. Epoxy graphene nano composites were characterized using X-ray Diffraction (XRD) and Fourier-Transformed Infra-Red (FT-IR) techniques and the thermal behavior of the composites is analyzed using thermogravimetric analysis (TGA).The desalination properties of the epoxy composites were investigated by using PH meter and Conductivity meter
