【Abstract】 SiO₂/P（MMA-MAA） microcapsule composite particles are prepared by the copolymerization of methyl methacrylate（MMA） and methacrylic acid（MAA） in the presence of silica（SiO₂） water soliquoid with sodium bisulfite（SBS） as initiator. The ER fluid is observed by microscope, and the photographes show that the ER fluid has ER effect. The stability of the ER fluid is improved. The dependence of the ER fluid’s shearing stress on electric intensity and percentage （wt） of dispersed particles is studied.更多还原
