Abstract: The current technology relates to various filter elements configurations where a substrate layer defines a surface having a treatment. The treatment increases a roll off angle of the surface for a 50 water droplet when the surface is immersed in toluene. The filter element can have a housing and the substrate disposed in the housing. In some embodiments the substrate layer defines a plurality of pleats extending between pleat folds that form flow faces of the media. In some embodiments the substrate is incorporated into single facer media of a filter element. In some embodiments the substrate layer is incorporated in a filter element having a flow-by configuration. In some embodiments the substrate layer is incorporated in a filter element having a cross-flow configuration. Some embodiments relate to a vent. Some embodiments relate to a barrier assembly and/or a fuel filter element. Various other filter elements are described.

Abstract: An article includes a permeable material having a surface; and a hydrophobic coating on the surface forming a hydrophobic surface, the hydrophobic coating being free of fluorine, and the hydrophobic surface having a water-contact angle of 95 degrees or greater. The article may be a vent. A method of making the hydrophobic article includes applying a hydrophobic material onto a permeable material; and curing the hydrophobic material to form a hydrophobic surface. The hydrophobic coating may include siloxane.

Abstract: A layered separation media includes a fibrous layer including a non-woven media; and a first coating disposed on the non-woven media, the first coating comprising a crosslinked hydrogel; and a membrane layer including a membrane; and a second coating disposed on the membrane. The second coating may also include a crosslinked hydrogel. The layered separation media may be used in a system for membrane chromatography. A method of separating a protein from a liquid stream may include flowing the liquid stream through the layered separation media. The protein may bind with functional groups in the hydrogel. The layered separation media may have a DBC10 of 50 mg/mL or greater.

Abstract: The current technology relates to filter media configurations where the filter media has a surface with a treatment that increases the roll off angle of the surface for a 50 μL water droplet when the surface is immersed in toluene. Some example filter media have a fluted configuration, and some example filter media have multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.

Abstract: A filter media comprises a layer of porous material having a patterned outer surface comprising a plurality of structures. Each structure in the plurality has at least a predetermined height based on an expected contaminant and spacing between each structure in a pair of structures in the plurality is at most a predetermined spacing based on the expected contaminant.

Abstract: Articles including poly(2,2,3,3,4,4,4-heptafluorobutyl methacrylate) or poly(2,2,3,3,4,4,4-heptafluorobutyl acrylate), fluoropolymers that do not form perfluorooctanoic acid (PFOA) when they degrade and that exhibit unexpectedly good oil repellency, are described. A method of making a fluoropolymer-containing article includes depositing a fluoropolymer-liquid mixture onto porous filtration medium by contacting the porous filtration medium with a mixture comprising a fluoropolymer and a liquid to form the treated porous filtration medium; and removing the liquid. The fluoropolymer includes poly(2,2,3,3,4,4,4-heptafluorobutyl methacrylate) or poly(2,2,3,3,4,4,4-heptafluorobutyl acrylate). Methods of using the article are further described.

Abstract: This disclosure describes compositions including a perfluoropolyether (PFPE) bottlebrush polymer, optionally blended with other fluoropolymers. The compositions may be disposed on an article, including, for example, a porous filtration media, to form a fluoropolymer-containing article. This disclosure further describes methods of making fluoropolymer-containing articles and methods of using the fluoropolymer-containing articles.
