Super-Absorbent Polymer: A Review on the Characteristics and Application

Super absorbency is superior swelling originates to absorb and retain large amount of aqueaous solution.Superabsorbent polymers are cross linked network of hydrophilic polymer chains.Poly (acrylate/).Poly (acrylate/acrylic acid) was synthesized to form superabsorbent hydrogel (SAH) and their performance as a water retaining aid for irrigation were assessed.The SAH acrylate/acrylic acid was cross-linked with N N'methylene-bis-acrylamide for optimum water retention.With today's demand for a one click solution, the development of superabsorbent technology has been largely directed by the needs of disposable hygiene segment, agricultural industry etc.Over the years, starch-grafted superabsorbent polymer turned into crosslinked acrylic homopolymers.Finally, the concept, mechanism and major application areas of superabsorbent are discussed well.
