PTFE coatings are widely used in non stick pans. But it is noticed that when metal is used instead of wood for sauteing it wears out easily. Can the fracture and flaking of the coating layer be improved by adding nano fillers ?
NANO (even naono-clay) should improve adhesive parameters, but nano is toxic because it is nano (smaller size just pass through cell walls), so maybe polymer/micro-ceramics composite would be the answer? Taking into consideration PTFE coating or others - even devices - all may be broken because of inappropriate tools used to operate it :)
Im not sure if PTFE "wears out easily" - it is easy to make scratch on PTFE (with knife, eg.) but I newer saw the PTFE layer just felt off the alumina surface.
Dear Murali Kakunje,
PTFE does exhibit a very low coefficient of friction, however, it is susceptibleto higher wear rates when compared to some other polymers. The addition of nanoparticles (especially platelet-shaped like graphene) can improve the wear resistance of PTFE. You are welcome to check out a paper that some of my colleagues and I have worked on.
Kind regards
