ABSTRACT:
An apparatus and method for forming a microfiber coating includes directing a liquid solution toward a deposition surface. The apparatus includes a tube defining a volume through which the liquid solution travels. An electric field is applied between the origin of the liquid solution and the surface. A gas is injected into the tube to create a vortex flow within the tube. This vortex flow protects the deposition surface from entrainment of ambient air from the surrounding atmosphere.
