Development of cellulose-based polymeric structures using dual functional ionic liquids

Abstract

Carboxylate ionic liquids combining benzethonium and didecyldimethylammonium as cations have been explored to be used for the first time as dual functional solvents for microcrystalline cellulose dissolution and, subsequently development of polymeric structures.

Evaluation of the multifunctional activity of silver bionanocomposites in environmental remediation and inhibition of the growth of multidrug-resistant pathogens

“…The polymeric chain of cellulose is linked by a β-glycosidic bond between two anhydroglucose units. 71 Electrostatic interactions ( i.e. , ion–dipole) occurred between the positively charged Ag ions and the negatively charged oxygen-rich molecules of the cellulose matrix.…”

“…The polymeric chain of cellulose is linked by a b-glycosidic bond between two anhydroglucose units. 71 Electrostatic interactions (i.e., ion-dipole) occurred between the positively charged Ag ions and the negatively charged oxygen-rich molecules of the cellulose matrix. 8 After impregnation into the polymer matrix, the electron-rich hydroxyl groups of cellulose reduced the Ag + ions to Ag(0) nanoparticles.…”

Recent Advances in Cellulose-Based Hydrogels Prepared by Ionic Liquid-Based Processes

“…The solvents dissolved cellulose efficiently at temperatures lower than 80 • C. The solvent DBN/PyO, at molar ratio of DBN and PyO of four, showed the cellulose solubility of 10.9 and 14.1% w/w at 50 and 70 • C, respectively. Galamba et al [83] studied benzethonium-and didecyldimethylammonium-based ILs combined with short alkyl carboxylate anions to dissolve MCC at a concentration of 4% w/w. The polymeric cellulose hydrogel structures varied depending on the type of ILs and the ratios between cellulose and IL.…”
