Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The porous membrane according to claim 1 , wherein the at least one polymeric feature is bonded by a molecular inter-reaction between a first material of at least one polymeric feature and a second material of the porous membrane. 3. The porous membrane according to claim 2 , wherein the at least one polymeric feature is bonded at a melting temperature of a lowest melting constituent of the first material and/or the second material. 4. The porous membrane according to claim 1 , wherein the at least one polymeric feature and/or the porous membrane comprise a chromatographic media. 5. The porous membrane according to claim 1 , wherein the at least one polymeric feature is porous. 6. The porous membrane according to claim 1 , wherein the pleated porous membrane has a first surface and a second surface and wherein the polymeric features are bonded to a portion of both surfaces. 7. The porous membrane according to claim 1 , wherein the pleats of the porous membrane include M pleats, W pleats, or a combination thereof. 8. The porous membrane according to claim 1 , wherein the at least one 3-dimensional injection molded polymeric feature has a cone shape, a bridge shape, a pyramid shape, a hexagon shape, or an hourglass shape.
