摘要
A novel liquid-liquid phase transfer method was employed to prepared nano titanate organosol. The hydrosol and organosol were investigated using UV-vis spectroscopy and laser particle size analyzer, and digital photos are used to exhibit the extracted effect. The results prove that the variety, concentration and HLB value of surfactant affect the phase transfer effect markedly. The as prepared organosol and hydrosol have a narrow size distribution. The phase transfer mechanism and the electrorheological effect of the organosol were studied. As the low current density, broad working temperature scale and good electrorheological effect, which under 3 kV/mm dc electrical field, the current density is low than 5 μA/cm2, electrorheological effect is 15 under 200 s-1. Dielectric property was also employed to explain the good electrorheological properties.
