Swelling, diffusion, network parameters and adsorption properties of IPN hydrogel of chitosan and acrylic copolymer

Synthesis, characterization and adsorption studies of an acrylic acid-grafted sodium alginate-based TiO2hydrogel nanocomposite

“…The adsorption capacities of different adsorbents for MV are listed in Table 2. It can be found that SA-g-PAA/TiO 2 absorbent is more efficient compared to those reported in previous literature (Bhattacharyya and Ray, 2014; 2013; Ghorai et al, 2014;Liu et al, 2011;Maity and Ray, 2014;Mandal and Ray, 2014;Mittal et al, 2015;Tian et al, 2010;Xu et al, 2011). This result indicates that SA-g-PAA/ TiO 2 hydrogel nanocomposite can be regarded as promising material for the MV removal from aqueous solution.…”

Chitosan/Xanthan Gum Based Hydrogels as Potential Carrier for an Antiviral Drug: Fabrication, Characterization, and Safety Evaluation

“…Upon further increase of polymer concentration from 8 to 12 g, reaction mixture got highly viscous and steric effect of CS outweighs ionic effect of ionic groups of the polymer, resulting in restricted movement of water molecules, leading to a lower swelling ratio. Thus, it can be assumed from results that optimum level concentration of CS that can enhance swelling behavior is 8 g. Beyond this concentration, swelling ratio decreases (Mandal and Ray, 2014).…”

Immobilization of laccase in a sponge-like hydrogel for enhanced durability in enzymatic degradation of dye pollutants

“…Besides, the properties of the resultant copolymers could be easily regulated by introducing prepolymers with particular functional groups. For example, hydrogel of CTS and acrylic copolymer with different swelling and diffusion characteristics were synthesized by varying the concentrations of CTS, initiator and crosslinker [14]. High hydrophilicity of hydrogel could be achieved by choosing prepolymers with polyelectrolytic nature or having abundant functional groups such as amine, carboxylic acid, hydroxyl, and sulfonic acid groups in the polymer chain [15].…”
