Right here is a current paper of our laboratory concentrating on the physico-chemical beginning of the thermoreversible residential or commercial properties of an organohydrogel constructed from polysaccharides. #greenchemistry
Abstract κ-Carrageenan was incorporated to an all-natural low-transition temperature level combination made up of fructose, glycerol, as well as water in a 1:1:5 molar proportion (FGW) to create totally biobased physical gels via a straightforward technique. The resulting gels can be conveniently prepared in different forms. When it comes to their hydrogel analogues, the rheological characterization of FGW-based examples confirmed thermosensitive gelation, credited to the development of aggregated H-bonded helices made up of κ-carrageenan chains. FGW-based gels display a gel − sol change temperature level (Tg/s) more than the among hydrogels with relatively easy to fix as well as recoverable viscoelastic residential or commercial properties upon succeeding heating/cooling cycles. SAXS evaluation exposed a much more prolonged conformation of chains in FGW that causes even more physical cross-linking joint areas within the products. Such strange spatial inner company supplies a mechanical support shown by compression examinations. To conclude, using the FGW solvent enables developing κ-carrageenan physical gels with improved mechanical as well as thermal residential or commercial properties.
