“…The N,N-methylene bisacrylamide (MBA) is a bifunctional molecule well-known for producing hydrogels based on acrylic acid (AAc) and acrylamide (ACL) [157]. However, in the last years, a lot of researches have been focused on the synthesis of hybrid materials based on polysaccharides, proteins, and monomers crosslinked via MBA, such as soy protein/AAc [158], gum acacia/alginate/AAc [159], alginate/chitosan/ACL [160], and Gel/Dextrin/ACL [161]. These materials are commonly prepared by free-radical polymerization (FRP), in which free radicals are triggered by a stimulus such as light, voltage, mechanical force, or chemical initiation [162,163].…”

“…However, the increasing MBA/ACL ratio can cause a phase separation process, decreasing the reaction rate. According to Priya and coworkers [161], for the synthesis of Gel/Dextrin/ACL hydrogel the optimum time and temperature were 150 min and 65 °C, respectively. The SD values determined for the resulting hydrogels achieved 345% with the increase of temperature reaction.…”

“…The concentration of coloured dye malachite green was examined using UV-Vis spectrophotometer (Priya b et al, 2020). The calibration curve was obtained between the varied concentrations from 2-10 mg/L with contact time of 95 minutes (till equilibrium) while taking 5 minutes interval at constant pH value of 7.0.…”

The objective of the present work is to fabricate environment-friendly biosorbent semi-Interpenetrating Network Device based on Psyllium-Okra hybrid backbone and acrylamide by using citric acid and ammonium persulphate as the crosslinker and initiator respectively. Response Surface Methodology (RSM) was used for the optimization of different reaction parameters that sequentially maximized the percentage swelling of the fabricated gel. Amalgamation of acrylamide chains onto Psyllium-Okra based hybrid backbone functional groups present and crosslinking between the different polymeric chains were further confirmed through techniques like FTIR, SEM-EDX and PXRD. The sample showed better thermal stability with decomposition of different phases at higher temperatures. The synthesized semi-IPN was successfully proved to be the proficient candidate for the removal of cationic toxic malachite green dye (62.38 %) with an adsorbent dose of 1.0 g, initial concentration of 10 mg L-1 and time interval of five minute at ambient temperature. Langmuir and Freundlich adsorption isotherm models were studied in order to determine the nature of adsorption took place and it was analysed that Langmuir adsorption isotherm was the best fit model for the removal of toxic cationic malachite green dye. Kinetic studies for the sorption of dyes favoured the reaction mechanism to occur via a pseudo second order pathway with R2 value about 0.99. The synthesized semi-IPN was also utilized in uranium (VI) uptake with an adsorbent dose of 1.0 g, initial concentration of 100 ppb, time interval of 55 minutes at room temperature. The semi-IPN could uptake 97.10 ppb uranium (VI) and was observed highly efficient in uranium (VI) ions removal from aqueous medium. Thus, adsorption studies indicated that semi-IPN prepared out of natural blend was found effective in the sequestration of toxic dyes and heavy metal ions.

Hydrogel is a three-dimensional cross-linked hydrophilic network that can imbibe a large amount of water inside its structure (up to 99% of its dry weight). Due to their unique characteristics of biocompatibility and flexibility, it has found applications in diversified fields, including tissue engineering, drug delivery, biosensors, and agriculture. Even though hydrogels are widely used in the biomedical field, their lower mechanical strength still limits their application to its full potential. Hydrogels can be reinforced with organic, inorganic, and metal-based nanofillers to improve their mechanical strength. Due to improved computational power, computational-based techniques are emerging as a leading characterization technique for nanocomposites and hydrogels. In nanomaterials, atomistic description governs the mechanical strength and thermal behavior that realized atomistic level simulations as an appropriate approach to capture the deformation governing mechanism. Among atomistic simulations, the molecular dynamics (MD)-based approach is emerging as a prospective technique for simulating neat and nanocomposite-based hydrogels' mechanical and thermal behavior. The success and accuracy of MD simulation entirely depend on the force field. This review article will compile the force field employed by the research community to capture the atomistic interactions in different nanocomposite-based hydrogels. This article will comprehensively review the progress made in the atomistic approach to study neat and nanocomposite-based hydrogels' properties. The authors have enlightened the challenges and limitations associated with the atomistic modeling of hydrogels.
