Water Thermal properties and mechanical properties of graphene nanoparticles and epoxy matrix were studied by S. Chatterjee and his co-workers. During the research graphene was modified by reacting with suitable amine compounds. Experimental results reveal that amine modification considerably improve affinity of graphene nanoparticles with the epoxy resin medium . A protective coating was synthesised by Saurav Ramesh Nayak et al. using epoxy resin and functionalized graphene. Graphene was modified with 4-fluoro phenol. The experimental data shows that addition of 0.25% graphene has improved the corrosion resistance of coating to a great extent. Author has reported that there is an increase in corrosion resistance by 30.46% by addition of 0.25 % functionalized graphene particles . A bio based protective coating was developed by Kamalon Rajitha and co-researchers. This eco-friendly coating is based on gelatingraphene oxide composite mixed with epoxy resin. Author initially modified gelatin with DETA (Di-ethylene triamine) to obtain modified geletin. The corrosion resistance of functionalised graphene were improved by reacting with geletin. Author revels that modification of graphene with geletin improved he corrosion resistance of coating by 59 % as compared to non-modified epoxy resin coating . Tafel polarization curve for the prepared coating are shown in Fig .
