| Summary: | The purpose of this study is to investigate the contact
mechanism between nanosheets and human fingertip skin
controlled to tens of nanometers in terms of friction coefficient under two different conditions, dry and immersed is. Nanosheets of various thicknesses with controlled film thickness were prepared, and the frictional force between the nanosheets and the fingertip was measured using a three component dynamometer. The contact area was observed with a prism and the contact area ratio was calculated. From the experimental results, comparing the friction coefficient and the contact area
ratio of the polymer nanosheet, it was found that the contact area
ratio increases as the friction coefficient decreases. In addition,
a much higher coefficient of friction was observed during drying
than when immersed in water, and the coefficient of friction
increased slightly with increasing load during immersion.
Therefore, the findings of this study could contribute to the study
of nanosheet mate rials and other skin applications. |
