Abstract
In this work, synthesis and swelling behavior of a super absorbent hydrogel based on alginate and polyacrylamide (PAAm) was investigated. the structure of the product was established using FTIR and SEM spectroscopies.The alginate-polyacrylamide hydrogel exhibited a pHresponsive swelling-deswelling behavior at pH’s 3 and 9. This on-off switching behavior provides the hydrogel with the potential to control delivery of bioactive agents.
Highlights
Among the diverse approaches that are possible for modifying polysaccharides, grafting of synthetic polymer is a convenient method to add new properties to a polysaccharide with minimum loss of the initial properties of the substrate
This article represents synthesis of a novel superabsorbent hydrogel based on alginate-gpolyacrylamide for control delivery system
To the best of our knowledge based on a precise survey of the Chemical Abstracts, the present paper is the first report on the preparation of a super absorbing hydrogel through graft copolymerization of a vinyl monomer onto alginate
Summary
Among the diverse approaches that are possible for modifying polysaccharides, grafting of synthetic polymer is a convenient method to add new properties to a polysaccharide with minimum loss of the initial properties of the substrate. Graft copolymerization of vinyl monomers onto polysaccharides using free radical initiation has attracted the interest of many scientists. This article represents synthesis of a novel superabsorbent hydrogel based on alginate-gpolyacrylamide for control delivery system. To the best of our knowledge based on a precise survey of the Chemical Abstracts, the present paper is the first report on the preparation of a super absorbing hydrogel through graft copolymerization of a vinyl monomer onto alginate
