The regularities of the laser UV radiation influence on the generation processes and the reactivity of volatile products of electron-beam dispersion of polyethylene, when zinc oxide and copper nanoparticles are introduced into the target, are determined. Under laser assisting action, the coating growth rate and the pressure in the vacuum chamber decrease, while the reactive activity of the generated volatile fragments increases. The coatings are characterized by a lower content of transvinylene bonds, the morphology — by less dispersion of structural formations. The coatings based on polyethylene of ultra-high molecular weight are characterized by higher defectiveness.
Keywords: electron beam dispersion, polyethylene, molecular structure, zinc oxide, copper.
