In late 2024, researchers at Northwestern University unveiled a graphene-oxide-based coating that could serve as a safe, high-performance alternative to per- and polyfluoroalkyl substances (PFAS) in food packaging. This innovative application underscores the diverse and rapidly expanding applications driving the global graphene market's growth. The innovation involves layering ultra-thin sheets of graphene oxide, which are naturally water- and oil-repellent, onto paper or cardboard substrates. The resulting material offers robust barrier properties, preventing grease and moisture migration without harmful chemical additives. Given the increasing regulatory push to ban PFAS in the US and Europe, this breakthrough could help transform the $60 billion food-packaging industry by providing a sustainable, food-safe solution.
