Title: ADHESION FORCES BETWEEN MICA SURFACES IN AIR AND LIQUIDS
Abstract: RESULTS From measurements in the air, it is found that the adhesion force remains constant under 30% R.H. or less and is insensitive to velocity of surface separation, v, and initial contact load, P. So we decided experimental conditions as follows: R.H.<20%, v=5 μm/s and P<3.9mN to ensure an elastic contact. Table 1 shows the results of present experiments, calculated values from eqs.[1][3] and experimental values in the past studies. It is clear that these values agree well except the values from eqn.[2]. We conclude from these results that (i)this new apparatus we developed detects surface interactions accurately and (ii)the adsorbed film must be considered in case of the interaction in the air but surfaces interact directly in the liquids. We can predict the force between mica surfaces immersed in these liquids using the equation[1] with an excellent agreement. These results suggest that the adsorbed film on the mica surface in the air will dissolve in the liquids used in the present study. ADHESION FORCES BETWEEN MICA SURFACES IN AIR AND LIQUIDS
