Surface modification method of filter membrane and composite filter membrane

Abstract

The invention discloses a method for modifying the surface of a filtering membrane loaded with a functional material through electrospray. The present method utilizes a melt bonding reaction between polymers (one in electrospray droplets and the other in the filtration membrane) to stabilize a functional material on the surface of the filtration membrane, thereby achieving multifunctionality of the filtration membrane and/or enhancing the performance of the filtration membrane. 本发明公开一种通过电喷雾负载功能性材料的过滤膜表面改性方法。本方法利用聚合物(一在电喷雾液滴中，另一在过滤膜中)之间的熔融键合反应以稳定具有功能性材料在过滤膜表面上，从而实现过滤膜的多功能性和/或增强过滤膜的性能。
