Research of Gas-Discharge Modification of Polymer Materials by Spectroscopy Methods
摘要
Abstract
The paper presents the results of studies of the influence of gas discharge modification on the physicochemical properties of polyethylene materials by FTIR spectroscopy, X-ray photoelectron spectroscopy and Raman spectroscopy. It was found that treatment of PE materials in radio-frequency gas discharge in air medium leads to oxidation of the surface layer, formation of polar hydroxyl, carbonyl and amino groups, increase in the content of C–O, C=O, C=C, C–N bonds, decrease in the supramolecular ordering of the polymer structure.
