“…After polymerization, a monolithic sample with high crosslinking was directly obtained by venting CO 2 ( Figure 1 b). When the sample was immersed in water, its original shape was still retained and achieved an opaque state, as depicted in Figure 2 g. Therefore, the porous hydrogel prepared through the present route was very different from those formed via the conventional synthesized method [ 19 ]. In particular, the gel was soft and dimensionally stable in this studied case.…”

Herein, a green, carbon dioxide-in-water high-internal-phase emulsion (C/W HIPEs) was developed and stabilized with polyvinyl alcohol (PVA) for the formation of chitosan oligosaccharide/poly(acrylamide-co-sodium 4-styrene sulfonate) [COS/P(AM-co-SSS)] monolithic porous hydrogel. The obtained monolith was characterized via FT-IR and SEM. The SEM patterns depicted that the monoliths were interconnected, the void sizes were 78.5 µm, and the interconnected pore throats were 28 μm approximately. Mechanical measurement results indicated that the maximum compress stress of the monolith could reach 334.4 kPa at 90% strain, and it exhibited good mechanical stability. After 200 cycles of compression, it could still recover its original shape without cracking. The obtained COS-based monolith was selected to remove tetracycline (TC) for evaluating the adsorptive features of the interpenetrating pore-containing monolith. The monolithic COS/P(AM-co-SSS) hydrogel behaved with strong antibiotic adsorption capacity (1600.4 mg/g for TC). The adsorption process agreed well with the pseudo-second-order kinetic and Langmuir isothermal models. In addition, the porous monolith had a strong electrostatic force on TC according to the thermodynamic study. This work provides a green route for the development of novel monolithic hydrogels and highlights its potential application in the treatment of antibiotic-containing wastewater.

“…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 ].…”

“…Due to the lack of use of initiators and cross-linking agents, among all of the methods, the gamma radiation technique is the most promising, effective, and prioritized for the preparation of pure gel. Gamma radiation is a highly energetic (<0.25 Å wavelength, >12 EHz (1 EHz = 10 18 Hz) and >50 keV energy) electromagnetic ray that can initiate copolymerization in both aqueous and non-aqueous solutions [ 17 , 20 ]. However, a detailed study regarding DMAA-DAM gels in non-aqueous solutions was not yet reported.…”

A few drugs need non-aqueous gels for release in the specific region of the intestine. The present work focuses on preparing N,N-Dimethyl acrylamide-Diallyl Maleate (DMAA-DAM) gel in Dimethyl sulfoxide (DMSO) solvent by applying different doses of gamma radiation and then characterization. The blend solution of 10%: 10%—DMAA: DAM was prepared in DMSO and irradiated at 2, 5, 10, 20, and 30 kGy doses from the Co-60 gamma source. After extraction, it was observed that all of the radiation doses yielded more than 95% gel content. The best gel content was found for 10 kGy dose, which was 97%. The equilibrium swelling was optimized 1800% of the dried gel for 5 kGy dose. Gel formation was confirmed by analyzing characteristic functional groups and the environment of protons in the gel structure by using FTIR and NMR spectroscopy. The thermal stability was tested using DSC and TGA which showed the glass transition temperature at 86.55 °C and the degradation started at 320 °C. The XRD pattern analysis revealed the semi-crystalline nature of the gel. Therefore, DMAA-DAM gels can be a good candidate for use in different fields of study, especially in drug delivery.
