Abstract
Described herein are nanofibers and methods for making nanofibers that include any one or more of (a) a non-homogeneous charge density; (b) a plurality of regions of high charge density; and/or (c) charged nanoparticles or chargeable nanoparticles. In one aspect, the present invention fulfills a need for filtration media that are capable of both high performance (e.g., removal of particle sizes between 0.1 and 0.5 μm) with a low pressure drop, however the invention is not limited in this regard.
