Abstract
Official abstract text for this publication.
A composite membrane for separations includes a substrate sheet with a non-woven array of nanotubes, and a dopant incorporated with the substrate sheet to form a non-porous, permeable composite. The composite membrane may be used to separate a target gas from a liquid by mounting the composite membrane in a housing chamber, and conditioning a permeate side of the chamber to establish a driving force for the target gas across the non-porous, permeable composite membrane.
First claim
Opening claim text (preview).
What is claimed is: 1 . A separation membrane, comprising: a substrate sheet of non-woven nanotubes; and a polymer dopant incorporated with said substrate sheet to an extent sufficient to form a non-porous, permeable barrier to fluid transport across the membrane. 2 . A separation membrane as in claim 1 separating a chamber into a retentate side and a permeate side. 3 . A separation membrane as in claim 2 wherein said barrier restricts fluid transport between said retentate side and said permeate side of said chamber. 4 . A separation membrane as in claim 1 wherein said polymer dopant includes an amorphous fluorocarbon.
