Preparation of aligned nanotube membranes for water and gas separation applications

Title: Preparation of aligned nanotube membranes for water and gas separation applications

Fabrication methods for selective membranes that include aligned nanotubes can advantageously include a mechanical polishing step. The nanotubes have their ends closed off during the step of infiltrating a polymer precursor around the nanotubes. This prevents polymer precursor from flowing into the nanotubes. The polishing step is performed after the polymer matrix is formed, and can open up the ends of the nanotubes.

Membranes having aligned 1-D nanoparticles in a matrix layer for improved fluid separation

Patent Revanur, Ravindra ; Lulevich, Valentin ; Roh, Il Juhn ; Klare, Jennifer E. ; Kim, Sangil ; Noy, Aleksandr ; Bakajin, Olgica

Membranes for fluid separation are disclosed. These membranes have a matrix layer sandwiched between an active layer and a porous support layer. The matrix layer includes 1-D nanoparticles that are vertically aligned in a porous polymer matrix, and which substantially extend through the matrix layer. The active layer provides species-specific transport, while the support layer provides mechanical support. A matrix layer of this type has favorable surface morphology for forming the active layer. Furthermore, the pores that form in the matrix layer tend to be smaller and more evenly distributed as a result of the presence of aligned 1-D nanoparticles.more »« less

Gas Separation Using Organic-Vapor-Resistent Membranes In Conjunctin With Organic-Vapor-Selective Membranes

Patent Baker, Richard W. ; Pinnau, Ingo ; He, Zhenjie ; Da Costa, Andre R. ; Daniels, Ramin ; Amo, Karl D. ; Wijmans, Johannes G.

A process for treating a gas mixture containing at least an organic compound gas or vapor and a second gas, such as natural gas, refinery off-gas or air. The process uses two sequential membrane separation steps, one using membrane selective for the organic compound over the second gas, the other selective for the second gas over the organic vapor. The second-gas-selective membranes use a selective layer made from a polymer having repeating units of a fluorinated polymer, and demonstrate good resistance to plasticization by the organic components in the gas mixture under treatment, and good recovery after exposure to liquidmore »« less

Process for fabricating PBI hollow fiber asymmetric membranes for gas separation and liquid separation

Patent Jayaweera, Indira ; Krishnan, Gopala N. ; Sanjurjo, Angel ; Jayaweera, Palitha ; Bhamidi, Srinivas

The invention provides methods for preparing an asymmetric hollow fiber, the asymmetric hollow fibers prepared by such methods, and uses of the asymmetric hollow fibers. One method involves passing a polymeric solution through an outer annular orifice of a tube-in-orifice spinneret, passing a bore fluid though an inner tube of the spinneret, dropping the polymeric solution and bore fluid through an atmosphere over a dropping distance, and quenching the polymeric solution and bore fluid in a bath to form an asymmetric hollow fiber.

Preparation of gas selective membranes

Patent Kulprathipanja, Santi ; Kulkarni, Sudhir S. ; Funk, Edward W.

Gas separation membranes which possess improved characteristics as exemplified by selectivity and flux may be prepared by coating a porous organic polymer support with a solution or emulsion of a plasticizer and an organic polymer, said coating being effected at subatmospheric pressures in order to increase the penetration depth of the coating material.
