Video: Why is Teflon so good at sticking?

If you have a pot, non-stick pan in your house, it must have been coated with Teflon to prevent food from sticking. What you may not know is why it can work so well.

Teflon is a polymer with a carbon chain in the middle and surrounded by fluorine.

Teflon , also known as polytetrafluoroethylene (PTFE), is a polymer with a carbon chain in the middle and surrounded by fluorine. Carbon and fluorine bonds are very strong, making them stick to each other instead of substances and it comes in contact. It almost does not react with other chemicals and has a low coefficient of friction, making it an ideal coating for nonstick kitchen utensils and some other items like raincoats, boots or circuit boards, as well as not decomposing when accidentally entering your body.

PTFE is coated on the object after its surface is sanded and spreads a layer of substrate, eventually only heating the object until everything is solid. When completed, it will form a smooth and conductive surface.
