摘要：
Membranes are provided for filtering a gas, in some cases air. Membranes using a highly porous cellulose nano fibrous barrier layer with a highly porous (surface-charged) substrate can exhibit high flux, high retention, and low pressure drop in air filtration of toxic aromatic gases, fumes, bacteria, viruses, dusts, and particulate matters.
