On the Evaluation of the Acidity and Basicity Parameters of the Surface Free Energy of Polymers

Abstract

Polymeric surfaces of polyvinylchloride and polymethylmethacrylate were found to be unsuitable when considered to be monopolar. The acid-base properties of these polymers were studied by using the Berger method, and their composition was analyzed by IR-spectroscopy and quantum chemical analysis. In order to determine the acidity and basicity parameters of the surface free energy (SFE) of smooth solid surfaces, the three-dimentional graphical method was proposed based on nonlinear Della Volpe modification of the van Oss-Chaudhury-Good equation.
