    Abstract: Polar molecules dominated electrorheological fluids mainly comprising a mixture of dispersed phase of solid particles and/or dispersing liquid medium. The dispersed phase solid particles, on the surface, or the liquid dispersing medium contain polar molecules or polar groups, the dipole moment of which is 0.5-10deb and the size is between 0.1nm and 0.8nm. Dispersed phase solid particles are spherical or nearly spherical, of which the size is 10-300nm and dielectric constant is higher than 50. The conductance rate of the liquid dispersing medium is lower than 10 -8 S/m, and the dielectric constant is lower than 10. The PM-ER fluids possess the characteristics of high yield stress, high dynamic shear stress, low leakage current, the linear dependence of yield stress on electric field, and high yield stress at low electric field, etc. The yield stress improves to almost 100 times of that of ordinary ER fluids and reaches to more than 200Kpa.
