Design and Development of Polysaccharide Based Polymer Blend

Abstract

The biodegradable polysaccharide chitosan is a considerably significant natural newlinebiomaterial with various application in biotechnology, pharmacology, and medicine on newlineaccount of its inimitable physicochemical properties, including acid-base behavior, newlineantimicrobial activity, biodegradability and mucoadhesive nature. The other most newlineabundant natural polymer is starch. Starch regenerates from carbon dioxide and water by newlinephotosynthesis in plants. Low cost and renewability and completely biodegradability, newlineconstruct starch a promising candidate for developing sustainable materials. newlineThe physical and chemical properties can be improved by the incorporation of other newlinenatural polymers with chitosan/starch through blending. Blending is an effective newlineapproach to achieve the required physical and chemical properties of the blended newlineproduct/films. Crosslinking is further an important phenomenon which takes part along newlinewith blending. Crosslinking agent/reagent is accountable for the establishment of newlinecrosslinks and/or intermolecular bridges between the polysaccharide molecules. newlineCrosslinking between the polysaccharides introduces a three dimensional network of newlinepolymer chains. newline
