Abstract
Herein, this innovative work; Poly(acrylamide-co-azomethine-co-acrylic acid) cogel is prepared in water as green solvent in order to study the effect of acrylamide content on swelling behaviour of hydrogels. It is found that hydrogels prepared in solution exhibited the highest swelling which probably extend it’s use in agricultural filed as well as in marine industry. The hydrogels is characterized by fourier transform infrared, elemental analysis, differential scanning calorimetry, thermal gravimetric analysis and field emission scanning electron microscopy. From Morphology study, we can see the change in porosity of cogel which is responsible for the absorbance of cogel. The results also indicated that the stability of azomethine is increased by formation of co-gel with poly(acrylamide–co-acrylic acid). In this report, straight forward and efficient synthetic protocol for cogel formation is adopted without any environmental hazard. Swelling capacity of P(AM-co-AA) and cogel was studied by addition of different saline solutions including monovalent, divalent, and trivalent salts. Its applications can be extended in agricultural industries as a basis for super absorbent polymer, waste water treatment, and even in medical field. Hence, the synthesized materials can be biodegradable, environment-friendly, and biocompatible inspired by the green
