| Research Abstract |
The purpose of this work was development of a measurement system for the surface property of thin liquid file, such as surface tension and viscosity, and generation of the scientific field in which the properties of thin liquid films were investigated especially. In this work, the oscillation of a micro droplet on glass plate is analyzed and the relations between the oscillation mode and surface tension and viscosity of liquid were obtained. In addition, a measurement system was developed in which the surface tension and viscosity were measured at one time and quickly even when the sample liquid had quite large viscosity. With this system, the dependence of the surface tension of melting polymer to temperature near the glass transition temperature was investigated.
