"oil molecules retain slippery, covalently-attached liquid surfaces from silicones or polyethylene glycol, both break down into harmless byproducts and are anti-adhesive without relying on problematic PFAS... liquid-like layers extremely slippery to most contaminants... increase efficiency heat transfer, collect water, prevent buildup of scale, and resist adhesion of ice and bacteria... neither too short, too long, packed too loose or too tight... fastest molecular diffusion where oil molecules right length and grafted with moderate density"
