Processing of Functional Composite Resins Using Deep Eutectic Solvent

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 the remarkable advantages of biocompatibility, economical feasibility and environmental hospitality, DESs show great potentials for green production and manufacturing. In terms of the processing of functional composite resins, DESs have been applied for property modifications, recyclability enhancement and functionality endowment. In this review, the applications of DESs in the processing of multiple functional composite resins such as epoxy, phenolic, acrylic, polyester and imprinted resins, are covered. Functional composite resins processed with DESs have attracted much attention of researchers in both academic and industrial communities. The tailored properties of DESs for the design of functional composite resins-as well as the effects of hydrogen bond on the current polymeric systems-are highlighted. In addition to the review of current works, the future perspectives of applying DESs in the processing of functional composite resins are also presented.
