A membrane should be able to regulate transmembrane transport of different substances and achieve selective permeation by allowing permeation of target substances while rejecting undesirable materials. A mesoporous polymer membrane derived from a microphase separated block copolymer precursor can be used as an ideal model system, as size- and interaction-dependent selectivity can be realized by permeation of substances through well-defined, size-controllable, and surface-tailorable mesopores. In this talk, I will highlight our recent progress in fabrication of such mesoporous membranes via polymerization-induced microphase separation (PIMS) process, which allows us to readily produce robust mesoporous membranes containing three-dimensionally continuous mesopore structure without additional aligning and postcrosslinking steps. I will discuss how the mesopore size and the surface functionality can affect the transmembrane transport and suggest potential applications of those membranes. |
