Abstract
A method of fabricating a polymeric film includes adsorbing an ammonium salt surfactant over a plurality of polymer beads. The method also includes adding the polymer beads to a polymer solution, wherein the ammonium salt surfactant substantially prevents flocculation of the polymer beads. Additionally, a polymeric film includes a plurality of polymer beads each having an outer surface. The polymeric film also includes an ammonium salt surfactant disposed over each of the outer surfaces, wherein the ammonium salt surfactant substantially prevents flocculation of the polymer beads.
