Electrospray Application for Creation of Smooth Thin Film Composite Membranes

Caption

A schematic illustration -- both top and side view -- of the 3-D printing electrospray process used to create extremely smooth thin film composite membranes that was developed in the McCutcheon Lab at the University of Connecticut. Needles loaded with solution of two monomers - m-phenylene diamine (MPD) and trimesoyl chloride (TMC) - use electrospraying to apply a fine layer of material to a substrate attached to a rotating drum. The monomers react upon contact to form an extremely smooth and thin polyamide film. Roughness and thickness can be adjusted by increasing or decreasing the monomer concentration in the solution and by applying additional layers of monomers on the rotating drum.
