Abstract

본 발명은 수투과성이 향상된 역삼투 복합 반투막의 제조방법에 관한 것으로, 좀 더 구제적으로는 복합 반투막의 다공성 지지체에 자외선을 조사하여 고분자 표면의 약 한 층을 제거하므로서 표면구조의 물리적 변화를 가져오고 고분자 표면에 극성의 관능기가 도입하여 역삼투 복합 반투막의 수투과성을 향상시키는 방법에 관한 것이다.The present invention relates to a method for producing a reverse osmosis composite semipermeable membrane having improved water permeability, and more specifically, by irradiating ultraviolet rays to the porous support of the composite semipermeable membrane to remove about one layer of the surface of the polymer to have a physical change in the surface structure. The present invention relates to a method of improving the water permeability of the reverse osmosis composite semipermeable membrane by introducing a polar functional group to the surface of the polymer.
