A non-stick surface is a surface engineered to reduce the ability of other materials to stick to it. A non-stick coating may be applied to a substrate to produce such a surface. One common application of non-stick coatings is cookware. Until recently PTFE (under the brand name "Teflon") dominated this market; however, due to health concerns regarding both the material (see Polymer fume fever) and its processing and application (see below regarding PFOA) its use has declined in recent years. Other coatings, including anodized aluminium and ceramics, have become popular.
Non-stick coatings are also used in lubrication applications.

Famous quotes containing the word surface:
“All forms of beauty, like all possible phenomena, contain an element of the eternal and an element of the transitory—of the absolute and of the particular. Absolute and eternal beauty does not exist, or rather it is only an abstraction creamed from the general surface of different beauties. The particular element in each manifestation comes from the emotions: and just as we have our own particular emotions, so we have our own beauty.”
—Charles Baudelaire (1821–1867)
