Multicomponent copolymers including two or more types of repeat units is presented. In one example, the multicomponent copolymer includes at least one repeat unit AC having a structure (I), at least one repeat unit DC having a structure (II), and at least one repeat unit BC having a structure (III) or (V). The multicomponent copolymer may be cross-linked via a cross-linking agent. A polymer blend including the multicomponent copolymer or a cross-linked copolymer and a second polymer is also provided. The multicomponent copolymer may be a random or a block copolymer. The structural units of the multicomponent copolymers provide improved, tunable properties, such as improved biocompatibility and hydrophilicity, protein fouling, and mechanical properties, to the copolymers and/or the membranes fabricated from the copolymers.
本文介绍了包括两种或多种类型重复单元的多组分共聚物。在一个例子中,多组分共聚物包括至少一个具有结构(I)的重复单元 AC、至少一个具有结构(II)的重复单元 DC 和至少一个具有结构(III)或(V)的重复单元 BC。多组分共聚物可通过交联剂进行交联。还可提供一种聚合物混合物,包括多组分共聚物或交联共聚物和第二种聚合物。多组分共聚物可以是无规共聚物或嵌段共聚物。多组分共聚物的结构单元为共聚物和/或用共聚物制造的膜提供了改进的可调特性,如改进的生物相容性和亲水性、蛋白质堵塞和机械特性。
