A kind of preparation method of imitating spider web structure oil-water separation membrane |
| abstract |
The invention provides an oil-water separation membrane imitating spider web structure and a preparation method thereof. In the invention, the polymer film is used as the base film, and the carboxymethyl cellulose (CMC) is used as the modifier to functionalize the polymer film, and the polymer film is introduced into the surface of the film by means of etherification and self-crosslinking to prepare the imitation spider web. The modified membrane of the structure utilizes the self-crosslinking of carboxymethyl cellulose to make carboxymethyl cellulose form a hydrogel layer on the surface of the polymer membrane, thereby realizing functional modification of the membrane surface. Compared with the unmodified polymer membrane, the carboxymethyl cellulose (CMC) polymer membrane prepared by the present invention has higher separation performance, anti-fouling performance and mechanical performance, and has certain reference for the research of separation membrane modification. value. |
