Researchers at the University of Illinois have proposed a design rationale for developing a family of cryoprotectant and phase change material-based compositions in the form of mixtures, non-aqueous emulsions-creams and gels. An in situ generated surface hydration layer protects the underlying substrate from a variety of foulants, varying from ice to disease-causing bacteria. Each formulation utilizes unique chemistry to curtail the embodied cryoprotectant loss and can be easily applied as an all-in-one sprayable/paintable coating capable of significantly outperforming untreated industrial materials in terms of their ability to delay condensation-frosting and shed ice simultaneously. They observed an array of formulation-specific functionalities which include optical transparency, mechanical durability, high shear flow stability, and self-healing characteristics…read more.
