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
文摘:利用原子力顯微鏡對石英巖表面單層分子沉積膜的微觀摩擦特性進行了研究，發(fā)現(xiàn)該分子沉積膜具有一定的減摩性.通過對其表面力-位移曲線、表面形貌像、調(diào)制力像和摩擦力像的進一步分析表明，石英巖表面分子沉積膜具有減摩作用的原因在于它能夠降低表面的粘著力并對表面具有微觀修飾作用
