Polyaniline Membranes for Gas and Liquid Separation.

Abstract : Membrane separation systems have gained attention recently as low cost energy-saving methods of purification. Mixture are separated based on chemical or physical interactions with the polymer membrane. Current membrane systems are limited by the difficulty involved in predicting polymer morphology prior to synthesis and in modifying of the polymer's morphology after film formation. However, polyaniline membranes can be tailored after film formation through the doping and undoping process. In this report we discuss the utility of polyaniline as liquid and gas separation membranes. Morphological changes to the polyaniline membrane and the effect these changes have on separations are explored. Gas separation, Pervaporation, Polyaniline, Membrane.
