Block polymers self-assemble into fascinating nanostructures driven by incompatibility between different polymer chains covalently connected to each other. Nanoporous polymers derived from block polymer precursors by etching a sacrificial component are particularly attractive for advanced separation applications because of precise control over the resulting structure and periodicity. In this talk, I will introduce polymerization-induced microphase separation where microphase separation is induced during concurrent polymerization/crosslinking via in situ block polymer formation. Mild etching of the resulting bicontinuous block polymer precursor produces a robust nanoporous polymer with percolating pores in the sub-10 nm range. Extraordinary advantages of this approach will be discussed including simple synthesis, three-dimensionally continuous porous space, precise control over pore size distribution and high mechanical integrity. |
