摘要：
A porous polymeric sheet (18) is provided having an electrostatic charge and comprising a zero-three composite of a polymeric matrix and a ferroelectric material dispersed therein. The polymeric component comprises a non-polar thermoplastic polymer, such as a polyolefin, and a second thermoplastic polymer having polar functional units, such as a telomer. The composite material is formed into a porous sheet (12) and is electrically or corona poled (26, 30) to create an electret material (18) which is well suited for use in various filtration, air-masking and dust wipe applications.
