- Abstract
Porous polymeric monoliths with densities as low as ≈0.060 g cm−3 are prepared in a gel-emulsion template way, of which the stabilizer employed is a newly discovered acidified aramid fiber that is so efficient that 0.05% (w/v, accounts for continuous phase) is enough to gel the system. The porous monoliths as obtained can be dried at ambient conditions, avoiding energy-consuming processes. Importantly, the monoliths show selective adsorption to HCHO, and the corresponding adsorption capacity ( M6) is ≈2700 mg g−1, the best result that is reported until now. More importantly, the monoliths can be reused after drying.
