The broader/commercial impact of this Small Business Technology Transfer (STTR) Phase I project focuses on developing an alternative coating to per- and poly-fluoroalkyl substances. These chemicals feature strong carbon-fluorine bonds that are extremely persistent in the environment and have recently been shown to be hazardous to human health. These per- and polyfluoroalkyl compounds are widely used in industrial and personal use applications, including as water-proof coatings for paper, clothing, and packaging materials, as surfactants, and as flame-retardant and stain-repellent coatings, among many other applications. This project will provide a replacement coating that is inexpensive, non-hazardous, and can be applied to a wide range of surfaces, such as for textiles or paper products, which are the project’s initial market targets. The technological innovation is based on a fluorine-free, earth-abundant mineral coating, using a class of material that is novel for these types of applications. This project will lead to barrier coatings that are durable, highly water and oil repellent, and resistant to scratching and corrosion. The final product will serve as a drop-in replacement substitute for these coatings. Phase 1 will focus on providing necessary data on the durability and industrial feasibility of the technology. This Small Business Technology Transfer (STTR) Phase I project focuses on generating a viable chemical coating that can replace current fluorinated coatin
