摘要:
The present invention relates to a method for the formation of virtually defect-free monolayers of particles with long-range order. The technique involves assembling the monolayer of particles on the interface between a solidifiable liquid and a fluid, which can be air or another liquid, ordering the particles using an electric field and then solidifying the former, e.g., by applying UV light. The monolayer becomes embedded on the surface of the solidified film. The monolayers can be coated onto the surface of materials to optimize their mechanical, thermal, electrical and optical properties.
