Teflon Lubrication: Chemical Persistence of Forever-Polymer Chains

Polytetrafluoroethylene (PTFE) is an engineered paradox. Better known as Teflon, it is the slipperiest solid material known to science, capable of shedding water, grease, and extreme heat without breaking a sweat. It revolutionized aerospace engineering and cookware by completely refusing to interact with its physical environment, but this exact chemical defiance is now recognized as a global biological hazard. The core of PTFE is the carbon-fluorine bond, which is so incredibly strong that it cannot be broken down by natural geological or biological processes. As these "forever chemicals" (PFAS) are shed from frying pans and industrial coatings, they accumulate permanently in the soil, the water table, and human bloodstreams. The industry is currently facing a reckoning, struggling to find alternative low-friction materials that don't leave a permanent, toxic legacy in the biosphere.
