摘要

Corona charging, triboelectrification and electrostatic spinning are three techniques to make charged media for filters. Charge retention life is independent of the charging techniques but depends on the electrical properties of the polymers as well as the fiber diameter and the medium structure. Charged media by triboelectrification had a higher charge density and FE but charging can only be achieved in carding process and it requires two dissimilar electronegative properties of the fibers. Both corona charging and triboelectrification were able to produce bipolar materials.
