Actually, it's quite simple. As you know,Teflon is a type of fluoropolymer, and therefore the surface energy is very low. In laymans terms, the halogenated hydrocarbon regions produce a non-polar molecular chain (duh). This gives the teflon, or PTFE (polytetra fluoroethylene)it's desireable properties, namely chemical resistance and very low surface tension. To make the polymer useful in the home consumer market, manufactures simply have to increase the surface energy to improve adhesion to the steel. This can be done in many ways. The most common, of course, is to increase the polarity at the surface by either a Corona Discharge or a chemical "etching". Either way, once the polarity has increased, bonding is elementary. By the way, polyolefins have the same issues, but you already knew that... Boy, I could just go on for hours about this stuff. Why don't you send me your home phone number so we can discuss this in further detail. You see, for some reason I have lost contact with most of my friends and family since I read the book "Know all, tell all".
