Processing of Functional Composite Resins Using Deep Eutectic Solvent

Crystals, 2020
Deep eutectic solvents (DESs)—a promising class of alternatives to conventional ionic liquids (ILs) that have freezing points lower than the individual components—are typically formed from two or more components through hydrogen bond interactions. Due to
