초록
본 연구에서는 폴리에테르술폰(PES) 중공사막을 수분 회수용 분리막으로 응용하고자 layer-by-layer(LbL) 코팅법에 의한 표면개질을 통하여 PES 중공사막의 수분회수능을 향상시키고자 하였다. PES의 술폰화를 통해 음이온성 sulfonated PES(SPES)를 합성하였고, 양이온성 고분자인 polyallylamine hydrochloride(PAH)와 함께 LbL 코팅수용액 제조에 사용하였다. 표면개질된 PES 중공사막의 특성 변화를 접촉각, ζ-potential, XPS, SEM 분석 등을 통해 관찰하였고, 수분투과도 및 선택도에 대한 성능평가를 실시하였다. LbL 코팅된 PES 중공사막은 50~80 nm 두께의 LbL 나노코팅층을 형성하였으며, 상대적으로 낮은 접촉각과 높은 수분투과도를 보였다. 본 결과를 통해 LbL 코팅법을 이용한 PES 중공사막의 표면개질은 표면 친수성 및 분리막 수분투과도 향상에 효과적임을 확인하였다.
Polyethersulfone (PES) hollow fiber membrane was surface-modified for application as a separation membrane to recover water vapor from the flue gas. Hydrophilic sulfonated PES (SPES) was prepared by introducing a sulfonic acid group in PES structure and was used for the layer-by-layer (LbL) coating solution with polyallyamine hydrochloride (PAH). The surface characteristics of the modified PES membranes were observed by XPS, SEM, ζ-potential and contact angle measurements. The formation of hydrophilic nano-coating layer with 50~80 nm in thickness on the surface of PES hollow fiber membranes by the LbL coating method led to relatively lower contact angle and higher water vapor permeance. As a result, the LbL coating method could be considered as a useful method for surface-modification of PES hollow fiber membrane to enhance their surface hydrophilicity and water vapor permeance.
