Hydrogels are well known networks of hydrophilic polymers which can absorb a significant amount of water without dissolving or loosing their structural integrity. The water content in the hydrogels affects various properties like permeability, mechanical properties, surface properties and biocompatibility and make them technologically useful materials as biomedical devices, absorbent products and chemical separators. This book is focused on the synthesis and characterization of sodium alginate based Interpenetrating Network hydrogels and the study of transport of a cationic dye Azure-B...
