Abstract
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.

A method for increasing an 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 comprises a C1-C10 alkanol or a mixture of H2O and the C1-C10 alkanol, wherein the ultrasonication is effected at a frequency in a range of 20 kHz to 2 MHz, a power input in a range of 5 W/l to 50 W/l, and a temperature in a range from 15° C. to 70° C.
