5710 Force Curve Measurement of Liquid Meniscus Bridge

Abstract

Characteristics of the force curve of a liquid meniscus bridge were experimentally investigated using a menisucus response apparatus that the authors developed. The force curves for relatively small or large contact angles were obtained. Difference between the maximum meniscus forces of the approach process and that of the release process was found and the hysteresis was observed. It was found that these phenomenon could be understood by considering the advancing and receding contact angles.
