The molecular dynamics simulation was used to investigate the adsorption of polymethyl methacrylate(PMMA) and polyvinyl acetate (PVA), the commonly used surface coating materials, on -quartz surface.The objective is to understand the interactions between quartz surface and polymers. The results clearly show adsorption of both polymers onto the quartz surface. Carbonyl group plays a significant role in the adsorption process. The adsorption energies of PMMA and PVA on -quartz surface did not show significant difference, however, more hydrogen bonds were observed on the PVA/quartz system than PMMA/quartz. These observations might offer some insights on the polymer–quartz adhesion and its failure mechanism.© 2015 Elsevier B.V. All rights reserved.
