The biggest problem in making non-stick pans
is making the PTFE stick to the pan. By its very nature, Teflon/PTFE is very inert and doesn't stick to anything. So clever chemistry has to be used to make it stick to the metal pan. But this impacts upon its non-stick properties, obviously, so you can't alter the chemistry too much. It's therefore a compromise between having something that food doesn't stick to and something which doesn't fall off the metal.

In practice, it doesn't work that well. And in time, due to heat degradation and whatever else, the lining will fall off.

Stick to Vipros's suggestion.
