This chapter reviews the current state of art polymeric nanomembranes and the concept and development of some mixed-matrix nanomembranes. Methods of controlling the pore shape, porosity, and size of nanoporous polymer materials are also reviewed, together with an analysis of a nano-blend with the nano-phase removed for controlled porosity. Finally, recent progress in mixed-matrix nanomembranes and nanomembrane multi-functionalization of various nanocomposites are discussed.

The nanomembranes most commonly used in membrane separation processes are polymeric materials. The separation is based on a dissolution and diffusion mechanism. This mechanism involves molecular-scale interactions of the permeating molecule with the membrane polymer. The mechanism assumes that each molecule is sorbed by the membrane at one interface, transported by diffusion across the membrane through the voids between the polymeric chains (or free volume), and desorbed...
