Observing different dynamic behaviors of weakly and strongly adsorbed polystyrene chains at interfaces.

Abstract

Understanding the dynamic behavior of polymer chains adsorbed onto a solid surface is of great importance for elucidating polymer-surface interactions. Here by using sum frequency generation (SFG) vibrational spectroscopy, we probed the conformational changes of weakly adsorbed and strongly adsorbed polystyrene (PS) chains on sapphire surfaces perturbed by… (More)
