Natural polymer-based cryogenically structured hybrid gels as support matrices were prepared by constructing synergistic multiple interactions among copolymer poly(2-hydroxyethyl methacrylate-co-glycidyl methacrylate) and different polysaccharides; hyaluronic acid (HyA), dextrin (Dex), maltodextrin (MDex), carboxymethyl cellulose (CMC) and xanthan gum (XG). Great improvement in thermal stability was achieved in the presence of CMC and MDex. In the as-prepared state, the highest modulus is observed in HyA-doped hydrogels, while in the swollen-state, CMC-doped hydrogels have a greater modulus. Hybrid cryogels showed higher swelling than hybrid hydrogels in all cases, while maximum swelling was obtained in HyA-doped hybrid cryogels. Solvent selection methodology based on solvent/polymer interaction was presented using 16 solvents with various solubility parameters. The PHG/XG network exhibited a more gradual swelling, whereas water uptake of hybrids doped with Dex and MDex were more pronounced dependent on temperature. The adsorption capacity of hybrid cryogels for methyl orange (MO) is both higher and faster compared to hydrogels, while a decrease in the adsorption capacity of hybrid cryogels at equilibrium was observed in the order of MDex > Dex > XG > CMC > HyA. This study provides a perspective on cryogenically structured hybrid material design by comparatively presenting the effectiveness of different polysaccharides that can be used for MO adsorption in water purification assemblies.
