Abstract
The disclosure describes a porous membrane including the following: at least one polymeric feature on a surface of a porous membrane wherein the at least one polymeric features are bonded to the membrane using a nanoscale injecting molding device. Another aspect of the disclosure includes a porous membrane including the following: a first film layer; a second film layer; at least one polymeric feature between the first film layer and second film layer, wherein the at least one polymeric feature is bonded to at least the first film layer.
Claims8
A porous membrane comprising:
- a pleated porous membrane having pleats forming alternating peaks and valleys with opposing membrane walls interconnecting the alternating peaks and valleys of the pleats;
- and
- at least one 3-dimensional injection molded polymeric feature formed on and bonded to a portion of at least one surface of at least one of the opposing membrane walls of the pleated porous membrane, wherein the at least one 3-dimensional injection molded polymeric feature comprises a structure formed of a polymer that is injection molded on the surface of the opposing membrane walls of the pleated porous membrane and separates the opposing walls of the pleats.
