  2. Abstract : molecular deposition ( md ) film, a nano film, is assembled by the interaction of static charge between cationic and anionic compounds. the micro - friction properties of an md film on silica has been studied with atomic force microscope ( afm ). it has been found that the md film has lower coefficient of friction as compared with the original surface of silica. moreover, based on the analyses of the surface force versus distance curves, photographic image, friction force image, and modulated force image, it is concluded that the friction reduction effect of md film on silica is attributed to the surface adhesion reduction and surface micro - modification
