Abstract

The present invention is a technique to fabricate thin-film composite perm-selective membranes by a transfer method. The composite membranes are useful in separating liquid, vapor or gaseous mixtures by selective permeation and reduce mass transfer resistance of the support layer. Selectivity and flux are improved by reduction of the mass transfer resistance of the support layer.
