  • ELECTROSPUN POLYMER NANOFIBERS WITH SURFACE ACTIVE QUATERNARY AMMONIUM SALT ANTIMICROBIALS
    Publication number: 20140221495
    Abstract: A fiber having a polymeric matrix and a quarternary ammonium salt. The quarternary ammonium salt contains at least one aliphatic group and no aromatic groups, is not covalently incorporated into the polymeric matrix, and is present on both the surface and in the interior of the fiber. The fiber may be made by electrospinning a solution of the polymer and the quarternary ammonium salt.
