| 摘要 | The invention relates to a carrier material having an inorganic molecular structure and a surface coating produced by applying a substance and by heat treatment. The invention also relates to a method for the production and to the appropriate uses of said surface coating. Carrier materials made of glass, metal or ceramic should be provided with a surface coating with anti-sticking properties against water-based and/or oil-based organic materials or water-oil emulsions while exhibiting at the same time essentially better temperature-resistant and anti-scratch characteristics than conventional PTFE or silicone coatings. These requirements are met by an inventive surface coating consisting of a combination of inorganic molecules of the carrier material and organic molecules of an applied substance on the uppermost molecular layer of said coating. In order to produce such a surface, an inorganic substance with silicone-like networks is initially applied. Subsequently, heat treatment is carried out, whereby the temperature and duration of said treatment are chosen in such a way that the purely organic coating applied is fully decomposed and/or removed so that a combination of inorganic molecules of the carrier material and organic molecules of the applied substance is formed. The appropriate carrier materials with the inventive surface coating can be advantageously used above all in household appliances and kitchenware. | ||||||
