Northwestern scientists find safer alternative to harmful PFAS chemicals

In recent developments at Northwestern University, scientists have made significant progress in creating a potential replacement for per- and polyfluoroalkyl substances (PFAS), commonly known as 'forever chemicals.' These synthetic chemicals are prevalent in various consumer products, such as cookware, cosmetics, and clothing, and have raised health concerns due to their persistence in the environment and human bodies. Studies have shown that PFAS are detectable in the blood of 97% of Americans, highlighting their widespread use and the potential risks associated with them. The research team, led by scientists including Wei from Go-Eco, a subsidiary of Chang Robotics, has been focused on exploring the properties of graphene oxide. This compound, derived from carbon, appears to present a viable alternative to PFAS, offering both environmental and health benefits. Graphene oxide can be applied to materials like paper to enhance their strength and make them resistant to water and oil, potentially replacing PFAS-based coatings currently used in food packaging and disposable products. Graphene oxide’s chemical structure allows it to alter the properties of paper without the harmful side effects associated with traditional PFAS. Unlike PFAS, graphene oxide is water-soluble, suggesting that it would not accumulate in the human body, mitigating the health concerns linked to 'forever chemicals.' With the ability to decompose naturally, graphene oxide may offer a solution for safer disposable products, allowing consumers to dispose of them without fear of leaching harmful chemicals into the environment. The long-term vision of the researchers is to create a range of materials suitable for food packaging, paper bags, and tableware, emulating the protective characteristics of plastic while promoting a healthier and eco-friendly approach to packaging and consumer goods. As the project progresses, it aims to align with growing public consciousness surrounding sustainability and health safety, signaling a possible shift away from materials that pose risks to human health and the environment.
