The Effect of a Metal-Substrate Surface on the Relaxation Behavior of Acrylic Coatings
Protection of Metals and Physical Chemistry of Surfaces（2022）
Abstract
The effect of the surface of an untreated and annealed copper substrate on the dissipative α-relaxation process in a highly elastic acrylic polymer is analyzed. The analysis is based on a comparison of the structural state and elemental composition of the metal surface, which are studied using physicochemical methods, with the intensity of internal-friction peaks, the glass-transition temperature, and the elasticity of the copolymer. The characteristics of the surface layer are correlated with the elastic properties of the polymer.
