Abstract

Electrospinning uses high voltages to form polymer nanofiber membranes. These membranes have potential for use in filtration, tissue engineering, drug delivery, and catalysis. The nonwoven fiber mat is malleable but has a low tensile strength compared to a solid film of the same polymer. Joining the fibers with a thin film is desired to balance the strength and flexibility. Three methods of producing a film on fiber membrane were tested. The techniques are spraying then melting, spin coating, and dip coating. Electrospinning setup conditions, solvent ratios, damage to fibers, and spin coating speeds were determined. Research was abruptly stopped and optimal dip coating conditions weren’t found. Final characterization of the membranes was also not completed. What was completed will facilitate similar work with electrospinning or finishing this experiment. Using a gas permeable film coating or varying the membrane area covered by film will build off of this research and make it more applicable.
