Abstract
Kaolinite/dimethyl sulfoxide intercalate was used as a precursor to prepare kaolinite/carboxymethyl starch intercalates by the displacement method. Intercalation of CMS into kaolinite collapsed the layer construction of kaolinite, which makes the single layers dispersed in the CMS. Intercalation improved the dielectric constant and conductivity of composite electrorheological fluid. The static shear stress of kaolinite/CMS composite ERF is 3.6 times of that of the pure kaolinite ERF and 2.24 times of the CMS ERF respectively. The electrorheological effect has the close relationship with the amount of CMS. The temperature effect of kaolinite/CMS ERF was improved and its antisedimentation is good.
