FILTERS WITH ELECTROSTATIC FILTERING CAPABILITIES
Filter media, triboelectrically charged fibers thereof, and methods for the same are discussed. The filter media may include a first plurality of fibers and/or a second plurality of fibers. The first plurality of fibers may be triboelectrically charged by the second plurality of fibers. The first plurality of fibers and the second plurality of fibers may include polylactic acid fibers and acrylic acid fibers, respectively. The first plurality of fibers and the second plurality of fibers may also include acrylic fibers and polypropylene fibers, respectively. The filter media may include one or more charge additives. A method for preparing the filter media may include contacting the first plurality of fibers with the second plurality of fibers, where contacting the first and second plurality of fibers with one another triboelectrically charges the first plurality of fibers.
