ABSTRACT:
Membranes for filtration by size exclusion are formed from open-ended nanotubes embedded in a polymeric matrix. The matrix forms a layer whose thickness is substantially less than the average length of the nanotubes, allowing the nanotubes to be randomly oriented throughout the matrix while providing channels extending through the layer for the selective passage of molecular species or particles based on size.
