Ultralow Resistance Two‐Stage Electrostatically Assisted Air Filtration by Polydopamine Coated PET Coarse Filter (Small 33/2021)

Air Filtration In article number 2102051, Jinhan Mo, Guiyin Xu, Ju Li, and co-workers develop a two-stage electrostatically assisted air (EAA) filtration device with stage-I plasma charging and stage-II polydopamine coated polyethylene terephthalate (PET) coarse filters. By controlling the surface microstructure of the filters, the authors report an EAA PDA@PET filter with a high filtration efficiency, low air resistance and large dust-holding capacity.
