Membranes and membrane separation techniques have grown from a simple laboratory tool to an industrial process with considerable technical and commercial impact. The book deals with both the fundamental concepts of preparation, characterization and modification, practical applications along with recent advancements of electro-spun and phase inverted polymeric membranes. Divided into two parts, part one of this book covers the fundamental concepts and practical applications of novel electro-spun membranes while the latter covers basic concepts and further advancements of the conventional phase inverted membranes extensively. Key Features Covers fundamental concepts and practical applications of electro-spun and phase inverted polymeric membranes Includes general properties, characterization, preparation and modification of polymeric membranes Discusses advanced modification of polymeric membranes (functionalization, grafting) using phase inversion process, and effects of solubility parameter and additives on the phase inversion process Reviews electro-spun membranes for biomedical applications, industrial effluents treatment and removal of water contaminants Explores a separate economic analysis section for the discussed membranes
