Atmospheric pressure plasma process for the production of plasma polymer coatings

摘要

The invention relates to a method for depositing a plasma polymer layer in an atmospheric pressure plasma on a metallic substrate, wherein the plasma is generated by a discharge between electrodes, characterized in that at least one organic coating precursor compound is fed into the region of the relaxing plasma and used as a plasma polymer layer on the metallic substrate is deposited, wherein nitrogen or forming gas is used as the process gas and the at least one organic coating precursor compound is selected from the group consisting of cyclic non-functionalized hydrocarbons and hydrocarbons having at least one functional group. The invention further relates to an article, an electrode and a capacitor, each comprising a metallic substrate having a surface and a plasma polymer layer on the surface, a method for producing the electrode, a method for producing the capacitor and a battery cell and a lithium Ion accumulator comprising the electrode.
