Application of semi-IPN network superhydrophilic membranes prepared on the basis of metal net for efficient oil-water separation, emulsion separation
Hydrogel, a common hydrophilic material, is often used in wastewater treatment. In order to expand the application of hydrogel in superhydrophilic coatings, we chose acrylic acid (AA) and methacryloyloyloxy ethyltrimethylammonium chloride (DMC), two chemical materials commonly used in wastewater treatment, and semi-interpenetrating networks (semi-IPN) based on the metal mesh structure were successfully polymerization, and a superhydrophilic membrane (PAA/PDMC@SSM(stainless steel mesh)) was prepared. The membrane ensures the efficient separation of different types of oil-water mixtures under high flux conditions (up to 99 % separation efficiency) and the effective removal of oil from water-in-oil emulsions. This green polymer material can be used for efficient oil-water separation as well as separation of water-in-oil emulsions (separation efficiency close to 98 %). In order to prevent microorganisms from clogging the separation membrane during wastewater treatment, it was tested for E. coli with 99 % inhibition. PAA/PDMC@SSM was found to be acid-resistant, durable and self-cleaning for viscous oils.
期刊介绍：
Colloids and Surfaces A: Physicochemical and Engineering Aspects is an international journal devoted to the science underlying applications of colloids and interfacial phenomena.
The journal aims at publishing high quality research papers featuring new materials or new insights into the role of colloid and interface science in (for example) food, energy, minerals processing, pharmaceuticals or the environment.
