POLYPHENOL-MODIFIED POLYMERIC MEMBRANE, PREPARATION METHOD THEREFOR AND METALLIZED POLYMERIC MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2023/155323
Kind Code:
A1
Abstract:
The present invention relates to the technical field of membrane materials, and particularly to a polyphenol-modified polymeric membrane, a preparation method therefor and a metallized polymeric membrane. According to the present invention, corona treatment is carried out on the surface of a polymeric layer, so that a polar modification liquid can uniformly coat the surface of the polymeric layer, thereby forming a modification layer closely combined with the polymeric layer, which imparts a relatively high level of lasting polarity to the surface of the polymeric layer with low polarity, so that the polymeric layer can be stably and closely combined with a layer of a material with high polarity and high surface tension such as a metallic layer for a long period of time, and thus the range of applications for non-polar polymeric substrate layers is effectively broadened; the concentration of the polyphenol and crosslinking agent in the modification liquid is controlled to allow the modification layer formed by crosslinking reactions to have a suitable crosslinking density and an adequate number of hydroxyl groups, so that the long-term polarity and surface tension of the polymeric layer can be increased more effectively and stably. The treatment process of the preparation method is simple, relatively cheap, efficient, and easy to scale up.
