摘要：

Semiconducting camphor-sulfortic acid doped polyaniline (PANI-CSA) particles were synthesized by chemical oxidation polymerization, and their chemical structure and particle size were examined via Fourier transform IR spectroscopy and scanning electron microscopy, respectively. Electrorheological (ER) fluids were prepared by dispersing the PANI-CSA particles in silicone oil, and their steady-shear rheological properties under electric fields were investigated using a rotational rheometer with a high-voltage generator. The PANI-CSA synthesized in this study possesses typical ER behavior:shear stress increases with increasing electric field strengths.
