Method for producing omniphobic surfaces, an omniphobic surface coating, uses of the omniphobic surface coating and the use in a heat exchanger

摘要

Method for coating components with an omniphobic surface coating, containing at least one organometallic scaffolding compound and an impregnating agent, with the steps,-electrochemical deposition of the organometallic scaffold compound on the component by electrolysis, from an electrolyte solution containing at least one metal ion, at least one linker compound and one solvent,-Application of an impregnating agent to the organometallic structure compound, whereby the metal ion(i) dissolved as metal ion salt in the electrolyte solution; and/or(ii) generated by electrolytic oxidation or reduction of a metal ion precursor contained in the component and/or electrode at the interface between electrode and electrolyte solution and/or provided in the electrolyte solution;and where the componenta) is simultaneously electrodeorb) placed in an electric field between at least two electrodesis,wherein the left compound is an organic compound of at least one tooth, and wherein the impregnating agent has a low surface tension of 30 mN/m.
