Abstract

The invention discloses a material with a specific surface structure for preparing a non-sticky pan. The lower surface of the material is planar, the upper surface of the material is concave-convex and is formed by the regular arraying of micron-sized hemispheres in an HCP (hexagonal close packed) manner, and nano-sized hemispheres are respectively distributed on the surface of each micron-sized hemisphere. By adopting the specific surface structure, the material can realize the non-sticky effect, thereby fundamentally avoiding damage and pollution to human beings and the environment by a harmful component namely PFOA (perfluorocaprylic acid) in Teflon used at present for producing the non-sticky pan.

Description

technical field [0001] The invention relates to a material with a specific surface structure, especially a material with a specific surface structure for preparing a non-stick pan. Background technique [0002] Since the product of non-stick pan came out, its "health" has always attracted people's attention. The non-stick pans currently on the market are able to achieve non-stick, mainly relying on the layer of "Teflon" coating on the bottom of the pan. This substance is the general term for fluorine-containing resins, including polytetrafluoroethylene, polyperfluoroethylene propylene and various fluorine-containing copolymers. Perfluorooctanoic acid ammonium (PFOA) is a necessary additive in the production of Teflon. PFOA with stable chemical properties will exist for a long time after entering the natural environment and human body, rather than decomposing quickly. Studies have shown that low doses of PFOA not only appear in rivers, oceans and soil, but also in people's ...
