Abstract  

The correlation between filtration efficiency and electret charge is investigated by means of measuring surface potential and filtration efficiency after solvent soakage in this paper. It is confirmed that the high filtration efficiency of melt-blown polypropylene nonwoven web is mainly originated from electret electrostatic effect and the filter resistance is determined by the fiber structure of nonwoven web. The stablity of electret electrostatic field depends on solvent swelling effcct on melt-blown polypropylene nonwoven web. Impact of solvent soakage on charge storage stability and filtration efficiency is thoroughly discussed according to the Flory-Huggins solvent swelling theory.

Key words:  organic polymer materials      solvent swelling effcct      filtration efficiency      electret air filter material      melt-blown polypropylene nonwoven web
