Porous polymeric monoliths with densities as low as approximate to 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 approximate to 2700 mg g(-1), the best result that is reported until now. More importantly, the monoliths can be reused after drying.
