Supported microporous ceramic membranes

Patent Webster, Elizabeth [Madison, WI]; Anderson, Marc [Madison, WI]

A method for permformation of microporous ceramic membranes onto a porous support includes placing a colloidal suspension of metal or metal oxide particles on one side of the porous support and exposing the other side of the porous support to a drying stream of gas or a reactive gas stream so that the particles are deposited on the drying side of the support as a gel. The gel so deposited can be sintered to form a supported ceramic membrane useful for ultrafiltration, reverse osmosis, or molecular sieving having mean pore sizes less than 100 Angstroms.

Methods for synthesizing microporous crystals and microporous crystal membranes

Patent Dutta, Prabir; Severance, Michael; Sun, Chenhu

A method of making a microporous crystal material, comprising: a. forming a mixture comprising NaOH, water, and one or more of an aluminum source, a silicon source, and a phosphate source, whereupon the mixture forms a gel; b. heating the gel for a first time period, whereupon a first volume of water is removed from the gel and micoroporous crystal nuclei form, the nuclei having a framework; and c.(if a membrane is to be formed) applying the gel to a solid support seeded with microporous crystals having a framework that is the same as the framework of the nuclei; d.more »« less

Solvent-resistant microporous polymide membranes

Patent Miller, Warren K [Bend, OR]; McCray, Scott B [Bend, OR]; Friesen, Dwayne T [Bend, OR]

An asymmetric microporous membrane with exceptional solvent resistance and highly desirable permeability is disclosed. The membrane is made by a solution-casting or solution-spinning process from a copolyamic acid comprising the condensation reaction product in a solvent of at least three reactants selected from certain diamines and dianhydrides and post-treated to imidize and in some cases cross-link the copolyamic acid. The membrane is useful as an uncoated membrane for ultrafiltration, microfiltration, and membrane contactor applications, or may be used as a support for a permselective coating to form a composite membrane useful in gas separations, reverse osmosis, nanofiltration, pervaporation, or vapormore » permeation.« less

Microporous membrane for stereolithography resin delivery

Patent Deotte, Joshua R.

A system for building a structure. The system includes a reservoir; an immiscible fluid in the reservoir; a membrane operatively connected to the reservoir; channels and delivery ports in the membrane; a microliter amount of curable resin; a delivery system for delivering the microliter amount of curable resin to channels and delivery ports in the membrane and to the reservoir in contact with the immiscible fluid in the reservoir; and an energy source adapted to deliver energy to the reservoir onto the microliter amount of curable resin for building the structure.

Inorganic dual-layer microporous supported membranes

Patent Brinker, C Jeffrey [14 Eagle Nest Dr. NE., Albuquerque, NM 87122]; Tsai, Chung-Yi [6 Mount Vernon Dr., Apt. C, Vernon, CT 06066]; Lu, Yungfeng [1055 N. Capital Ave., #20, San Jose, CA 95133]

The present invention provides for a dual-layer inorganic microporous membrane capable of molecular sieving, and methods for production of the membranes. The inorganic microporous supported membrane includes a porous substrate which supports a first inorganic porous membrane having an average pore size of less than about 25 .ANG. and a second inorganic porous membrane coating the first inorganic membrane having an average pore size of less than about 6 .ANG.. The dual-layered membrane is produced by contacting the porous substrate with a surfactant-template polymeric sol, resulting in a surfactant sol coated membrane support. The surfactant sol coated membrane support ismore »« less
