表面修饰无机粒子亲水改性聚醚砜膜的研究进展OA

Polyether sulfone(PES)was widely used in the field of wastewater treatment due to its excellent antioxidant properties,hydrolysis resistance,thermal stability,and mechanical performance.However,PES membranes are hydrophobic,which can easily lead to membrane fouling and a shortened service life during the separation process,thereby limiting their application in the water treatment field.Therefore,it was necessary to modify PES membranes to be hydrophilic in order to enhance their antifouling properties.The commonly used membrane modification methods included surface modification and blending modification.The article introduced the preparation and modification methods of PES membranes,with a focus on the research progress of hydrophilic modification by surface decoration with inorganic particles.At the same time,it analyzed the challenges faced by inorganic particle-modified PES membranes,providing references for further research.
