Patent ID: 8257798

Claim:
A method for variation of sizes or distances in patterns of nanostructures on a substrate, comprising a) contacting a substrate with a liquid phase that contains micelles of an organic two-block- or multi-block copolymer, said micelles being charged with an inorganic metal compound, by immersion into the liquid phase, during which chemically different polymer domains comprising metal compounds enclosed in micelles are deposited on the substrate; b) withdrawing of the substrate from the liquid phase at a predetermined withdrawing speed, which withdrawing speed is varied continuously or gradually, so that a gradient of a lateral separation length of the polymer domains is produced on a substrate surface; c) conversion of the metal compounds in the deposited polymer domains by an oxidation- or reduction treatment into inorganic nanoparticles and optionally complete or partial removal of the organic copolymer by a plasma treatment, wherein positions and a lateral separation length of the nanoparticles obtained are determined by positions and a lateral separation length of the deposited polymer domains.
