Abstract

This paper aims an analysis on the correlation between various plasma effects on polymers treated under a particular experimental configuration, dielectric barrier discharge-type. Experiments are carried out to relate relevant surface properties, as surface energy components, surface topography, structural changes and chemical composition, under conditions where plasma processing allows complex surface modification, by combined functionalization and crosslinking to polymer characteristics. In this respect, the degree of modification of the surfaces, in terms of adhesion work increase, incorporation of polar groups, crystallinity enhancement, is shown to depend both on the sample polarity prior to treatment and on the respective chemical structure of polymers, showing also correspondence with the crystallinity and average size of crystalline regions..
