I believe it is possible using advanced temperature control techniques for coils, especially in disposable devices which are more consistent across units and are less liable to be tampered with, to coat the coils with a fluoropolymer like Teflon (PTFE) or PFA while still preventing the coatings thermal depredation and production of harmful byproducts. This would, in theory, eleminate catalytic oxidation of juice resulting in fewer harmful oxidation products and lead to a better and more consistent taste over time.

Coils coated in this way would also be way easier to clean and way less likely to accumulate "crud" overtime because the primary mechanism for creation of such cruds is catalytic oxidation and subsequent polymerization of vape juice compounds easily sticking to the porous and inevitably textured surface of the metal (not to mention the increased chemical bonding of the crud to metals due to van der Waals forces which would be virtually absent from fluoropolymers).

Even ceramics don't offer this benefit as they are almost by definition porous. The coating should have a smooth surface down to the nano level, be chemically inert and not "sticky". All of these could be achieved with fluoropolymer coatings and when combined with the increasingly cheaper advances in forms of temperature control, could be very safe and effective.

What do you guys think?

Full disclosure: I do have a university and self-taught background in chemistry, physics, materials science and nanotechnology.

Even still I'm interested in challenges to my idea, criticisms and constructive feedback.
