Investigation of nanofriction and nano-scale properties of silica surface using atomic force microscopy

摘要

The nano-scale surface roughness and the nanofriction of silica surface were measured in ambient condition using atomic force microscopy(AFM). The nano-scale properties of the sample were investigated The correlation between the fractal property and frictional coefficient of the silica surface was investigated It has been found that the frictional force is proportional to load. The surface adhension force and elastical modulus of silica surface were measured. Moreover, The nanoscale dynamic processes during the tip of AFM contacting the surface of sample were analysed Therefore, it is possible to link the nano-scale properties of sample with its nanofriction behavior.
