In 2016, researchers developed a prototype de-icing system that incorporated unzipped carbon nanotube graphene nanoribbons in an epoxy/graphene composite. In laboratory assessments, the main edge of a helicopter rotor blade was coated with the composite, covered by a protecting metal sleeve. Making use of an electrical current heated the composite to over 200 °F (93 °C), melting a 1 cm (0.4 in)-thick ice layer with ambient temperatures of a -four °F (-20 °C). In 2014, researchers on the College ...
