In the present study, three kinds of biodegradable superabsorbent hydrogels, such as PAA/chitosan, PAA/guar gum, and PAA/pectin, were synthesized using acrylic (AA) acid as a monomer and reinforced with three different biopolymers, such as chitosan, guar gum, and pectin, as reinforcing materials separately. In this work, N, N'-methylenebisacrylamide is used as a cross-linking agent and ammonium persulfate (APS) as an initiator. The polymerization was carried out through an emulsion polymerization process. All three synthesized biomaterials are subjected to a test of swelling behaviour, which is characterised by UV–Vis and FTIR spectroscopy. From TGA analysis, the zone weight loss was found between 430 and 580 °C, 320–600 °C, and 400–600 °C for PAA-CS, PAA-GG, and PAA-PEC, respectively. From the biodegradability test, the reduction of mass is observed at a rapid rate and increases with time. The SEM image indicates the porous structure of the three biomaterials. Among the three biomaterials, PAA-PEC shows the maximum water absorbency. The rate of drug release is higher at pH = 7.4 as compared to pH = 1.2.
