23 Jul Responsiveness-based copolymer modified polypropylene (PP) micro-filtration membrane
Abstract
The invention provides a responsiveness-based copolymer modified PP micro-filtration membrane, belonging to the field of functional polymer materials. According to the invention, polyethylene glycol methacrylate (PEGMA), diethylaminoethyl methacrylate (DEAEMA) and methyl methacrylate (MMA) are used as copolymerization monomers and undergo free radical polymerization to synthesize responsive three-component random copolymer P (PEGMA-co-DEAEMA-co-MMA); the responsiveness of the PP micro-filtration membrane is modified by using a surface entrapment method, and the wettability and surface morphology of the membrane can be regulated and controlled by changing the concentration and variety of a modification agent, treating temperature, etc.; and the amounts of water permeation of the PP micro-filtration membrane under different pH value conditions before and after modification. The responsive PP micro-filtration membrane with controllable surface morphology and performance obtained in the invention is expected to be used as an intelligent responsive material in the fields like tissue engineering and oil-water separation materials.
