| 摘 要： | Composite particles consisting of polyaniline(Pan )core and barium titanate(BaTiO3) layer shell were synthesized. The PAn-BaTiO3 composites particles were characterized with TEM and XRD. The dielectric behavior of particles was tested and the electrorheological (ER) behavior of the suspensions of PAn/BaTiO3 parti-cles in chlorinated paraffin oil with a 20vol% was investigated under DC electric field.The results show that the ER effect of composite particle is far stronger than that of pure polyaniline and barium titanate which were synthe-sized by the same methed. PH and thickness of BaTiO3 have an important influence on the ER effects.

| Abstract: | Composite particles consisting of polyaniline (PAn) core and barium titanate (BaTiO3) layer shell were synthesized. The PAn-BaTiO3 composites particles were characterized with TEM and XRD. The dielectric behavior of particles was tested and the electrorheological (ER) behavior of the suspensions of PAn/BaTiO3 particles in chlorinated paraffin oil with a 20 vol% was investigated under DC electric field. The results show that the ER effect of composite particle is far stronger than that of pure polyaniline and barium titanate which were synthesized by the same method. pH and thickness of BaTiO3 have an important influence on the ER effects.
