High surface area polyHIPEs with hierarchical pore system
Abstract
The synthesis of polyHIPEs with bimodal pore-size distribution and very high specific surface areas up to 1210 m2 gā1 is reported. Monolithic polyHIPE precursors were swollen, and subsequently the polymeric network was crosslinked in the expanded state by internal and external electrophiles under catalysis of a Lewis acid leading to hypercrosslinked
