为赋予高分子膜特种功能如亲水、吸附、催化等，从分子设计入手，通过在传统膜材料聚砜、聚醚砜和聚偏氟乙烯等主链上引入功能嵌段，设计合成嵌段共聚物膜材料。
Block copolymers are designed and synthesized to incorporate the specific functionality including hydrophilicity, absorption, and catalytic properties into the polymeric membrane materials including polysulfone, polyethersufone, and polyvinylidene difluoride.
