Ultrafiltration (UF) membranes, particularly membranes fabricated from self-assembled diblock copolymers, hold promise in wastewater treatment, dairy, and food industries. Membrane development goals involve combining a highly porous selective layer with a narrow pore size distribution with a mechanically stable supporting layer to achieve constant flux. To date, isoporous integral asymmetric membranes have been formed either as flat sheets or hollow fibers, and a surface-selective layer determines membrane separation performance. A unique isoporous membrane of the poly(4-vinylbenzocyclobutene)-b-poly(4-vinylpyridine) (PVBCB-b-P4VP) diblock copolymer with a substructure of almost homogeneous porosity throughout the body of the material (three-dimensional porosity) has been developed. Moreover, the matrix of the membrane (PVCB) enables it to undergo cross-linking, allowing the membrane to be thermally sterilized and applied in high-temperature UF applications.

热和化学稳定的等孔嵌段共聚物膜

超滤 (UF) 膜，特别是由自组装二嵌段共聚物制成的膜，在废水处理、乳制品和食品工业中大有前途。膜开发目标涉及将具有窄孔径分布的高度多孔选择性层与机械稳定的支撑层相结合，以实现恒定通量。迄今为止，等孔整体不对称膜已形成为平板或中空纤维，表面选择性层决定了膜的分离性能。聚（4-乙烯基苯并环丁烯） -b-聚（4-乙烯基吡啶）（PVBCB- b）的独特等孔膜-P4VP) 二嵌段共聚物在整个材料体（三维孔隙率）中具有几乎均匀孔隙率的子结构。此外，膜的基质 (PVCB) 使其能够进行交联，从而使膜能够进行热灭菌并应用于高温 UF 应用。
