摘要：
A separation matrix comprises a porous surface layer; and a bulk porous support, wherein both the porous surface layer and the bulk porous support comprising a block copolymer. The block copolymer comprises A-B or A-B-A repeating units, wherein A and B at each occurrence are two different blocks of oligomer, or polymer. A structural unit of block A is derived from one or more atom transfer radical polymerization (ATRP)-active monomer or oligomer and a structural unit of block B is derived from a thermoplastic ATRP-active macro initiator. A poly dispersity index of the block copolymer is at least about 2.
