Illinois team creates graphene-enhanced gilding process for protective coatings
Gilding is the process of coating intricate artifacts with precious metals. Ancient Egyptians and Chinese coated their sculptures with thin metal films using gilding—and these golden sculptures have resisted corrosion, wear, and environmental degradation for thousands of years.

In a new study at the University of Illinois at Urbana-Champaign, Sameh Tawfick was inspired by this ancient process and used it with a twist – he added a layer of graphene on top of palladium metal leaves—doubling the protective quality of gilding against wear and tear.
