The rugged surface produced by the nanoparticle coating on a substrate is very effective to prevent water adhesion and maintain the transparent. So, we developed the novel water repellent using nanoparticle for side mirror of a car. The rugged surface by coating is also very effective to prevent powder adhesion too. It was experimentally confirmed to prevent dust adhesion by covering the surface of the glass substrate with nanoparticle. The adhesion force between particle and substrate is measured by the centrifugal method and the relation between the adhesion force and the surface roughness is discussed from experimental and theoretical point of view. The measured and calculated results by Van der Waals force show that adhesion force decreased with the increment of the surface roughness. From the results, nanoparticle coating is very effective to prevent the dust adhesion on the substrate and the various application of nanoparticle coating can be expected.
