Researchers from the University of Illinois at Chicago discovered several unique properties of materials known as phase-switching liquids (PSLs) that hold promise as next-generation anti-icing materials. PSLs are a subset of phase change materials that have melting points higher than the freezing point of water.

While researchers have known about phase change materials for a long time, their unique anti-icing and anti-frosting properties have not been investigated before. PSLs could be used to coat objects like car windshields or turbine blades without compromising the object’s functionality.
