Abstract: Abstract Although emulsion-templated aerogels could be advantageous over polyHIPEs, their hypercrosslinking has not been explored yet. Herein, we report hypercrosslinking emulsion-templated syndiotactic polystyrene (sPS) aerogels through Friedel-Crafts alkylation to generate hypercrosslinked, hierarchically porous sPSs. The… read more here.
