Synthesis and Characterization of Gamma Radiation Induced Diallyldimethylammonium Chloride-Acrylic Acid-(3-Acrylamidopropyl) Trimethylammonium Chloride Superabsorbent Hydrogel

Abstract

The gamma radiation technique is simple and time-saving for the synthesis of pure hydrogels. The present work focuses on synthesizing and characterizing Diallyldimethylammonium Chloride-Acrylic acid-(3-Acrylamidopropyl) trimethylammonium Chloride (DADMAC-AAc-APTAC) superabsorbent hydrogels. The hydrogels were synthesized by applying gamma radiation of different doses (2 kGy to 30 kGy) to two different compositions of monomers. The equilibrium swelling was found to be 33483.48% of dried gel for a 1:0.5:1 composition ratio of monomers at a 2 kGy radiation dose. Therefore, on the basis of equilibrium swelling, 2 kGy is the optimum radiation dose for synthesizing the hydrogel. Fourier transform infrared (FTIR), nuclear magnetic resonance (NMR) spectroscopy, and X-ray diffraction (XRD) characterization techniques were used to analyze and confirm the structure of the hydrogel. Thermogravimetric analysis (TGA) and Scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS) clearly showed the thermal stability and surface morphology of the gel. Therefore, it can be concluded that hydrogels can be used in metal adsorption, drug delivery, and other fields of study.

Radiation-Induced Hydrogel for Water Treatment

“…The hydrogels prepared through the interaction between a specific form or electromagnetic radiation and polymers or monomers have vast fields of app Based on the radiation method used, the hydrogels can be classified as shown in The radiation method proceeds through the formation of free radicals from solvents (H 2 O), polymer backbones, and monomers. The effect of radiation on raw materials is dependent on the energy and frequency range of the applied dose, as well as the types of polymers, solvents, and monomers [47,48]. We choose the radiation based on the criteria that the hydrogels must meet; for instance, we synthesize highly pure hyaluronic acid/chondroitin sulfate-based hydrogels for biomedical applications using gamma radiation [9].…”

“…Such hydrogels exhibit outstanding performance in dye adsorption, positioning them as viable candidates for eco-friendly water purification methods. This methodology capitalizes on gamma radiation’s crosslinking strengths alongside the inherent polysaccharide framework of potato starch, further augmented by acrylic acid, to effectively purify water by eliminating pollutants [ 66 , 67 , 68 ].…”

“…A few of the SHs are very effective in selective metal adsorption [5], drug delivery [6], dye adsorption [7], wound dressing [8], and biomedical applications [9]. The essential properties of hydrogels are swelling, mechanical strength, and re-usability, which can be enriched through grafting/cross-linking between different monomers/polymers [10,11]. SHs encounter irreversible damage after de-swelling, which can be attributed to the absence of a suitable energy dissipation mechanism.…”
