| 논문초록 | Microporous polymers are widely used owing to their high surface area and small pore size (< 2 nm). Hierarchically porous polymers (HPPs) containing micropores within 3D continuous mesoporous framework (2 – 50 nm) are appealing materials showing enhanced adsorption performance by promoting diffusion through the mesoporous space. We have developed a synthetic route to HPP by combining polymerization-induced microphase separation (PIMS) with hyper-cross-linking that can create micropores in the wall of percolating mesopores templated by the block polymer self-assembly. This methodology allows us to finely tune the pore characteristics at the micro- and mesoporous levels. The hierarchical pore structure has proven to enhance the sorption kinetics both in the gas and the solution state. Efforts to construct a conjugated HPP framework that can respond to sorption of target molecules by changing fluorescence will be discussed. |
