The previous studies mainly focused on the adsorption ofbiological molecules onto inorganic surfaces, while the study ofinteraction between polymer and quartz is few. In thisstudy, we report the structural and thermodynamic behaviorbetween -quartz and two common polymers (PMMA and PVA)in dry condition. Equilibrium all-atoms molecular dynamics (MD)simulations were used to study the whole system in vacuum. All-atoms molecular dynamics simulation is an effective computer
