Novel multilayer structural epoxy nanocomposite coating for enhanced adhesion and protection properties of steel
Joseph Raj Xavier
Abstract
This work is aimed to synthesize novel structural epoxy nanocomposites containing graphene oxide (GO) and 3-(trimethoxysilyl) propyl methacrylate (TMSPMA) modified W2C. The coating resistance of EP-GO/TMSPMA-W2C was additionally noticed to be over 44.9% higher than that of pure matrix. The GO/TMSPMA-W2C was enriched in the degradation products, forming an excellent passive layer at the coating/steel interface. The newly designed EP-GO/TMSPMA-W2C nanocomposite coating had improved protection against corrosion and excellent hydrophobic characteristics (WCA: 159°). The incorporation of graphene oxide enveloped W2C in the epoxy matrix resulted in improved adhesion strength, tensile strength and hardness properties.
