METHOD FOR COATING A COMPONENT WITH A LAYER MADE OF A METAL-ORGANIC FRAMEWORK AND A COMPONENT COATED WITH A LAYER MADE OF A METAL-ORGANIC FRAMEWORK

摘要

According to the invention, a method is provided for coating at least in areas a component with a layer of a metal-organic framework (MOF), in which the body is contacted with a solution containing at least one metal salt (MOF precursor), at least one linker, and at least one solvent. The linker in this case can effect the bonding of the MOF layer to the surface of the component and/or the structure of the MOF layer. The method is characterized in that the solution has a temperature gradient, wherein the temperature of the solution immediately at the surface of the component permits the crystallization of an MOF layer on the surface, whereas the temperature of the remaining solution prevents the formation of MOF crystals in the remaining solution. The method can be used for producing components having layers of defined chemical and/or physical properties. Furthermore, the invention comprises components which have at least in areas an MOF layer. A possible use of said components is in sorption refrigeration machines.
