Polysaccharide Based Superabsorbent Polymer : A Review

It is a need of time to synthesize and verify the natural biopolymers to reduce the threats to health and environment. The superabsorbent polymers are hydrophilic structure which makes them capable of holding large amount of water in their three dimensional networks. Polysaccharides are highly abundant biopolymers with a variation of structure and properties. They are non-toxic, biocompatible and biodegradable so potentially substitutes the synthetic polymers. Due to their attractive properties, they are used as a rheological modifier in food, pharmaceutical, paper, textile, oil, drilling and score of other industrial and agriculture sectors. This review sheds light on different technologies adopted for SAP materials production based on polysaccharide as green biosources and their applications. The methods used for quantifying the SAP practical features are discussed as well.
