Research Abstract

1. (1) Rheological behavior of the colloidal suspensions of silica spheres and sodium montmorillonite flakes in the exhaustively deionized aqueous media were investigated in the presence of small amounts of sodium chloride. The viscosity of the flake system initially decreased and then increased as the concentration of the sodium chloride increased, the tendency of which is different from the sphere system.
(2) The sodium montmorillonite flakes in organic solvents became stable as the dielectric constant of the solvents increased, and the electrical double layer in organic solvents was considered to be thinner than that in the aqueous system.
2. (1) The fullerene nano-particles were well-dispersed in a press film of polystyrene and the composite film was stable at high temperatures.
(2) Solid films were prepared from isotropic solutions of cellulose derivatives and the solutions suspending titanium dioxide nano-particles. The initial process was sensitively monitored by the polarized opti … More cal microscopy and the dynamic viscoelastic measurements. The dynamic viscoelastic behavior would be sensitively affected by the local behavior of the sample around the edge of the fixture. The process just before termination was sensitively monitored by the dielectric measurements. In the solid film prepared under the electric field with a large amplitude, a uniaxial-like orientation was found and the helix axis was perpendicular to the electric field.
3. (1) Rheological monitoring was found to be more effective than the electrical monitoring of the curing process for a reactive silicone.
(2) Apparent electrical properties changed during the electrical orientation process of the carbon nano-fiber in suspension.
(3) Orientation behavior was investigated under sinusoidal electric field for anisotropic solutions of cellulose derivatives and the solutions suspending multi-walled carbon nano-tubes after shearing. The electrical properties depended on the directions of the initial shear and the electric field. Less
