  • Patent number: 10287451
    Abstract: A composition of matter is described in which a porous material, such as polydimethylsiloxane (PDMS), is coated with parylene N, C, D, or AF-4 by vapor deposition polymerization while a temperature of the porous material's surface being coated is heated to between 60° C. and 120° C., or 80° C. and 85° C., during deposition. The parylene forms nano roots within the porous material that connect with a conformal surface coating of parylene. In some embodiments, a watertight separation chamber in an integrated microfluidic liquid chromatography device is fabricated by heating tunnels in micro-fabricated PDMS and depositing parylene within the heated tunnels.

  • Patent number: 10164227
    Abstract: A degassing valve for degassing a housing of a motor vehicle includes a support element coupled to the housing, a membrane that is water-proof and breathable, and a tensioning frame configured to press the membrane against the support element with a pressing force. The tensioning frame is configured such that when a pressure difference between an interior of the housing and a surrounding of the housing exceeds a trigger force, the membrane detaches from the support element and exposes a fluid channel between the interior of the housing and the surrounding of the housing. The exposed fluid channel is configured to degas the interior of the housing.

  • Patent number: 9675937
    Abstract: A permeate carrier to be described in detail below has side edges, alternatively called borders, that are thinner than a central part of the permeate carrier. Adhesive is applied to the side edges to form a seal when a membrane leaf is formed around the permeate carrier. After the membrane leaf is wound around a central tube, the side edges extend in a spiral around the central tube. The transition between the side edges and the central part of the permeate carrier helps prevent adhesive from flowing into the central part of the permeate carrier. The reduced thickness of the side edges also reduces an increase in diameter at the ends of an element that might otherwise be caused by the adhesive.

  • Patent number: 8926732
    Abstract: The present invention provides gels, solutions, films, membranes, compositions, and other materials containing polymerized and/or non-polymerized room-temperature ionic liquids (RTILs). These materials are useful in catalysis, gas separation and as antistatic agents. The RTILs are preferably imidazolium-based RTILs which are optionally substituted, such as with one or more hydroxyl groups. Optionally, the materials of the present invention are composite materials comprising both polymerized and non-polymerized RTILs. The RTIL polymer is formed from polymerized RTIL cations typically synthesized as monomers and polymerized in the presence of the non-polymerized RTIL cations to provide a solid composite material. The non-polymerized RTIL cations are not covalently bound to the cationic polymer but remain as free cations within the composite material able to associate with charged subunits of the polymer. These composite materials are useful in catalysis, gas separation, and antistatic applications.

  • Publication number: 20140131263
    Abstract: A barrier of open pore mesh provided with a superhydrophobic coating to prevent wetting when exposed to an aqueous liquid. The disclosed barrier could be a mesh screen or a liquid pervious membrane. The barrier is useful in a filter media containment to permit egress of gas, usually air, from the containment even when subjected to an aqueous liquid containing environment.

  • Patent number: 8684189
    Abstract: Described is the application of layer-by-layer (LbL) electrostatic assembly techniques to electrospun nanofibers in order to fabricate novel, breathable electrospun fiber-based chemical and biological detoxifying protective fabrics and filters. The combination of layer-by-layer electrostatic assembly and electrospinning technique allows one to take advantage of high specific surface area, light weight and breathability of electrospun fiber mats while simultaneously providing the versatility to incorporate different functional polyelectrolytes to achieve multifunctional coatings for both chemical and biological protection together. The functionalized fiber mats can be incorporated into breathable chemical and biological protective fabrics, filters and masks. In addition, LbL electrostatic coating of porous non-woven materials provides the versatility to generate multifunctional polymer-based membrane materials for other applications.
