摘要：
Herein, self-assembled core-shell micelles of amphiphilic comb copolymer imitating the structure of fish scales was employed to tune the surface structure and surface properties of PES membrane. Numerous papillae with a diameter of 100-200 nm were fabricated on membrane surface, which effectively improved the performances of the resultant membrane. Upon modification, water contact angle of the membrane was decreased from 78.3 degrees to as low as 43.8 degrees, while the flux recovery ratio was increased from 61.2% to as high as 97.4%. This study provided a facile way for the fabrication of composite membranes with regular surface structure. (C) 2018 Elsevier B.V. All rights reserved.
