Hierarchically porous polymers containing pores across multiple length scales from micro- (＜ 2 nm), meso- (＞ 2 nm, ＜ 50 nm) to macroporous (＞ 50 nm) regimes are expected as one of promising materials for separation, templating, and adsorption. We propose a new route to preparing hierarchically porous polymers with interconnected micro-, meso- and macropores with controlled pore size and high porosity (＞ 90%) by combining hyper-cross-linking, block polymer self-assembly, and polymerized high internal phase emulsions (polyHIPE). Hierarchically porous polymers consisting of multiscale pores of 1 nm, 10 nm, and 1 μm length scales were successfully produced with orthogonal control of pore size at each length scale and mutually interconnected pore structure. We also demonstrate that the hierarchical pore structure is critical for rapid and efficient adsorption of dyes from aqueous solution. |
