Production of bicomponent polymer droplets by electrospraying

Electrospraying is a method of generating a fine mist through electrostatic charging. It is used for producing polymer droplets at submicron range, which enhances functional properties of the substrate after deposition by providing thin level coating and larger surface area. In this research, in order to impart multifunctionality to substrate, the two distinct polymers thermoplastic polyurethane (TPU) and poly vinyl chloride (PVC) are electrosprayed simultaneously by specially designed nozzle. Energy dispersive spectroscopy (EDS) was used to confirm the bicomponent droplet fabrication. The results show that new electrospraying system demonstrated the feasibility of producing bicomponent TPU/PVC polymer droplets.
