抄録

A new method is proposed for measuring both solid-liquid contact angle and liquid surface tension. When a circular cilinder is horizontally immersed into a liquid bath and is lifted up gradually, a pair of two-dimensional liquid meniscus is formed under the side wall of the cylinder. At a certain critical height of the cylinder, the waists of the two meniscus curves contact with each other and the break-down of the meniscus occurs. Since the relation between the critical height of the cylinder H_BCr and the contact angle θ can be calculated theoretically, θ can be obtained by a simple measurement of H_BCr . The liquid surface tension also can be measured by using a grass cylinder to which most liquids attach at θ=0. The validity and usefulness of the method was expeimentally confirmed for various solid and liquid samples.
