A study of bacterial cellulose confined ionic liquid and deep eutectic solvent gel materials
… are liquid at or below 100[degrees]C, as well as deep eutectic solvents (DESs), a mixture of a hydrogen bond donor with a strong hydrogen bond acceptor that remains liquid upon cooling, have been popularized as greener alternatives in industry. These liquids tend to have large electrochemical and …

Multi-techniques Characterization of Mechanochemically Synthesized Deep Eutectic Solvents
<p>Deep eutectic solvent (DES) is the alternative and greener solvent in which two compounds, usually a hydrogen bond acceptor (HBA) and a hydrogen bond donor (HBD), are used. Two components form a complex network with strong intermolecular forces and show a lower melting point than those of the …

Non-Covalent Interactions in Polymeric Materials: From Ionomers to Polymer Blends
… as compared to sulfonated PET-containing blends. Deep eutectic solvents (DES) have been reported to be the next generation solvents due to the superior biocompatibility, biodegradability, and sustainability as compared to ionic liquids. Two types of deep eutectic solvents, choline chloride : malic …
