Patent ID: 7655383

Claim:
A method for manufacturing nanometrically surface-decorated substrates comprising the steps: (a) depositing a core-shell polymer system, prepared by taking up a polymer in a suitable solvent with formation of a dissolved core-shell polymer system and loading of at least part of the polymer cores with one or more, identical or different metal compounds, as a film onto a substrate so that at least one side of the substrate is configured in a regular structure, (b) irradiating said polymer film on the substrate as obtained in step (a) through a desired mask, by exposure to a source of radiation selected from visible light and ultraviolet light in the range from 410 nm to 157 nm that causes a chemical modification of the polymer in the irradiated areas, (c) removing the non-modified core-shell polymer system from the substrate by means of dissolution with a suitable solvent, and (d) removing the polymer core-shell system as irradiated in step (b) while producing metal clusters and/or metal compound clusters on the substrate without thereby significantly modifying the structure erected by the core-shell system; wherein the polymer is selected from poly(isoprene)-b-poly(2-vinylpyridine), poly(isoprene)-b-poly(4-vinylpyridine), poly(isoprene)-b-poly(ethyleneoxide), poly(butadiene)-b-poly(2-vinylpyridine), poly(butadiene)-b-poly(4-vinylpyridine), poly(butadiene)-b-poly(ethyleneoxide).
