Researchers at the University of Toronto have developed a new material that repels oil and water like traditional non-stick coatings, but uses far less PFAS, the harmful “forever chemicals” linked to serious health and environmental risks.
The team created a microscopic brush-like structure using PDMS (a safe silicone used in medical implants). Each bristle tip carries a tiny PFAS molecule, minimizing chemical use while maintaining performance.
The coated fabric scored a 6 on the industry oil-repellency scale, matching standard PFAS coatings but with lower toxicity and no bioaccumulation.
