Research Abstract

Basic study for micro-mixing of materials with focused ultrasound was carried out. It was found that irradiation of focused ultrasound with continuous wave into bounded field is not efficient for generating streaming and that use of burst wave with appropriate interval effectively generates a streaming. With this method, a technique for regulating micro-structure in the processing of high-viscosity materials proposed.
New methods of material characterization utilizing acoustic imaging and ultrasonic nonlinearity were developed. With the imaging method, two-dimensional image of materials were obtained with high resolution. Basic technique for characterizing films, fibers, and particles immersed in water was proposed on the basis of higher harmonics of propagated waves. The crystallinity of polymers and particle size in suspensions were estimated with the proposed method.
The effects of strength and direction of electric and magnetic fields on the flow properties of iron suspensions were e … More xamined by using the two rheometers for parallel-field and crossed-field conditions. Significant synergistic effect was observed under the parallel-field condition. Normal stress measurements under an electric field revealed that comb-shaped liquid crystalline polymers form an induced network structure. Opposite ER effects were observed for urethane polymers with different terminal groups.
Flow properties of block and graft copolymers having microphase separated structure and ionomers having ionic aggregation were studied. The relation between molecular structure and flow properties was clarified in terms of the micro-strusture.
A simulation program for crystallization in injection molding was suggested. This simulation technique was found to be useful for the flow analyzes under various conditions.
High-speed convergence flow of various polymer melts were studied by measuring the pressure and temperature during the flow, and analysis of the shape of extrudates. It was found that the characteristic behaviors depending on the molecular structure can be explained with the nonlinearity of the extensional viscosity of the polymers. Less
