Highly ordered arrays of micelles or nanoparticles on a substrate surface and methods for producing the same

摘要

The invention provides a method for increasing the order of an array of polymeric micelles or of nanoparticles on a substrate surface comprising a) providing an ordered array of micelles or nanoparticles coated with a polymer shell on a substrate surface and b) annealing the array of micelles or nanoparticles by ultrasonication in a liquid medium which is selected from the group comprising H₂O, a polar organic solvent and a mixture of H₂O and a polar organic solvent. In a related aspect, the invention provides the highly ordered arrays of micelles or nanoparticles obtainable by the methods of the invention.
