Patent attributes
A composite comprises a chemical, mechanical and/or optical protective and/or diffusion barrier layer disposed on a metal or plastic substrate. The layer consists of an organic layer matrix with metal-containing particles dispersed therein, the metal-containing organic layer being plasma-polymerized starting from at least one hydrocarbon which can be substituted and one metal-containing component. The protective and/or diffusion barrier layer is used in a thickness (d) in the submicron range and contains metal particles finely dispersed therein, that have a grain size that lies below 50% of the layer thickness (d). The organic layer matrix is deposited by plasma polymerization from a process gas that comprises at least one hydrocarbon that can also be substituted and one metal-containing component and/or an inorganic gas in a reactor that can be evacuated.
