Research progress in hydrophilic modification methods of polyethersulfone membranes for water treatment
Polyethersulfone(PES)membranes are a class of high molecular polymer membrane materials with excellent comprehensive performance,which have wide applications in water treatment.However,due to its hydrophobicity and lipophilicity,PES membranes are prone to contamination in water,resulting in decreased membrane permeability and shortened service life.In order to enhance its anti-pollution performance,it can be hydrophilic modified.This article introduces three common hydrophilic modification methods,namely surface coating modification,surface grafting modification,and blending modification.Among them,the blending modification method has the most advantages in the application of water treatment due to its significant modification effect,simplicity,and convenience.It is hoped that this article will provide a reference for further modification research of polyethersulfone membranes.
