Research Abstract

1, Effect of the electric field, magnetic field, ultrasonic wave field and flow field on the microstructure was investigated.
(1) The in-situ observation of the electro rheological (ER) fluid, the magneto rheological (MR) fluid and the electro magneto rheological (EMR) fluid was performed. The relation between the rheological behavior and the field induced structure of the particle aggregation was clarified.
(2) Orientation of the micro fibril particles in polymer melt was studied and explained by a simple model.
2, Computer simulation of the rheological behavior of the materials under the external field was performed. The mechanism of the structure growth in the ER,MR and EMR fluid was described by a simple model.
3, In order to control the microstructure, ultrasonic wave was examined. It was found that by the tone-burst wave, acoustic streaming was generated efficiently in a thin material.
4, The effect of the molecular structure, molecular weight distribution, particle size and particle shape on the microstructure controlling was investigated. It was shown that for the case of the EMR fluid, the field induced network structure was closely related to the inhomogeniety of the particles.
5, The mechanical properties of the structure-controlled materials was examined by the impact tests.
