1. A method of making a nonwoven mat comprising one or more antimicrobial agents, comprising:
- providing a dispersion comprising;
a fluorinated polymer;
a fiberizing polymer;
one or more antimicrobial agents; and
a solvent;
electrospinning said dispersion to give a mat precursor; and
heating said mat precursor at a temperature and for a time sufficient to remove said solvent and said fiberizing polymer, in order to form a nonwoven mat.

Abstract
A method of preparing antimicrobial-containing polymeric products is provided, the method involving electrospinning a dispersion comprising a dispersible polymer, a fiberizing polymer, and one or more antimicrobial agents. The electrospun material is heated to remove solvent and the fiberizing polymer, giving a nonwoven polymeric material having antimicrobial agent incorporated therein. The material can be in the form of, for example, a non-woven sheet, tube, or covering.
