They roughen the pan's surface by sandblasting it. A primer is applied to the surface and then the Teflon is embedded in the primer.
The idea is quite simple - the Teflon won't chemically bond to anything else, but you can mechanically get it stuck in small cracks and crevasses.

If nothing sticks to Teflon®, then how does Teflon® stick to a pan?
Non-sticks are applied in layers, just like paint. The first layer is the primer - and it's the special chemistry in the primer that makes it adhere to the metal surface of a pan. The primer will adhere either to a substrate that is prepared by grit blasting or roughening the surface, or it can be applied over a smooth substrate.
This is directly form website.
Teflon is very slippery, because of a layer of electronegative fluorine atoms on its exterior (which try to repel materials in close contact.) To stick to the pan, it is physically bonded to surfaces, not chemically, almost like velcro. It's like how ice gets stuck in ice-tray; the ice isn't actually stuck to the tray, just wedged in, and that's how Teflon is stuck to surfaces.
Working with Teflon is difficult in any case. The molecular chains are extremely long, typically 100,000 carbon atoms long. It does not melt easily (it is used for high temperature applications) and is a very viscous liquid even when it does melt. Teflon is attached to surfaces by sintering it from a powder. At a high enough temperature, the molecular chains begin to move about somewhat so that they bind together into a continuous material. They also enter pores and crevices in the surface and becomes wedged inside when it cools. With enough of its chains extending into the pan surface, the whole Teflon sheet is permanently attached to the pan.

Teflon is only "non-stick" in its solid form. When they spray it while it is still a liquid, it will stick. After it hardens, things will not stick to it.

That is a deep question. I don't know the answer. Teflon has come into disfavor because it Teflon lines your intestines and is probably a carcinogen.

now the answer to this extremely pressing matter is so important to me that i decided to take it to my superiors. a man known only as Mr. Smith told me the answer. apparently, Mr. Smith says that lots of little men are in the microscopic gap between the two materials (teflon and copper, say) and these men hold them together in rehersal for the worlds strongest man. its just like the elephants in the super absorbant bounty.

Yahoo needs to be coated in TEFLON to stop this question being stuck in here time and time again.
