Abstract
The features of the molecular structure and morphology of polyethylene (PE) and polyvinyl chloride (PVC) based coatings, deposited from the products of repeated electron beam dispersion of the original polymer, are determined. Macromolecules coatings obtained by repeated dispersing of PE, contain a high concentration of unsaturated bonds and short-chain branching. The coating is formed by highly dispersed lamellar, “spiral” formations. The effect of the electron beam on PVC initiates the processes of dehydrochlorination, the formation of a polyconjugated structure. Recycled PVC-based ratings contain mainly graphite-like structures and polyene fragments, have regular pores of 300-700 nm in size, high abrasion resistance, which determines their effective use as an antibacterial layers matrix.
