| 中文摘要 | The core–shell structural dielectric particles are applied widely in the electrorheological (ER) fluids. The properties of the dielectric core are critical factors influencing their ER activity. In this paper, we successfully synthesized two kinds of core–shell hydroxyl titanium oxalate (TOC) particles with SiO2 and TiO2 as core, respectively. The obtained core–shell structural SiO2ATOC and TiO2ATOC particles were welldispersed spherical nanoparticles with ideal morphology and a narrow size distribution. Under DC electric fields, the TiO2ATOC ER fluid showed notable ER activity with a yield stress of about 96 kPa (at 4 kV/ mm), which is 3 times of that SiO2ATOC ER fluid and outclassed the yield stress of the TOC ER fluid. The dielectric spectra indicated that the higher dielectric constant of TiO2 core induces the stronger interaction between the neighboring particles, which contribute to the enhancement of ER activity. |
