Preparation of a Cu-BTC/PAN electrospun film with a good air filtration performance

Copper-1,3,5-benzoic acid (Cu-BTC) was synthesized by the hydrothermal method, which had regular octahedral morphology. The Cu-BTC particles were used as additives in the polyacrylonitrile (PAN) solution fabricate Cu-BTC/PAN membrane by the electrostatic spinning method, its good filtration performance was witnessed experimentally.
