Abstract

A brief review of the literature data on the treatment of polymer membranes by alternating and unipolar corona discharge is presented in this work. Treatment by corona discharge in air leads to the formation of ozone, which contributes to the formation of oxygen-containing groups (C–O–C, C–OН, C(O)OН, C–O, and C=O) on the membrane surface of carbon-chain polyolefin, polysulfone, polyethersulfone, polyetherketone, polyvinyl chloride, and other polymers, as confirmed by IR spectroscopy. This contributes to an increase in hydrophilic characteristics, wettability, and polarity of the membranes, and an increase in the roughness of the latter by burning, as shown by atomic force microscopy, scanning electron microscopy, and the sessile drop technique. Hydrophilization of polymeric membranes after corona treatment results in improved performance during the ultrafiltration of media containing microorganisms, albumin, oil-water and petroleum-water emulsions, etc.

电晕放电对聚合物膜的改性

摘要

在这项工作中简要回顾了有关通过交替和单极电晕放电处理聚合物膜的文献数据。通过空气中的电晕放电处理导致臭氧的形成，这有助于形成含氧基团（C–O–C，C–OН，C（O）OН，C–O和C = O）红外光谱证实，碳链聚烯烃，聚砜，聚醚砜，聚醚酮，聚氯乙烯和其他聚合物的膜表面。如原子力显微镜，扫描电子显微镜和固着滴技术所示，这有助于增加膜的亲水性，润湿性和极性，并通过燃烧增加膜的粗糙度。
