SYNTHESIS AND ELECTRORHEOLOGY OF PHOSPHORIC ACID DOPED POLYANILINE SUSPENSIONS

초록

Semiconducting phosphoric acid doped polyaniline (PANI-H3PO4) particles were synthesized by chemical oxidation polymerization, and their chemical structure and particle size were examined via Fourier transform IR spectroscopy (FTIR) and scanning electron microscopy (SEM), respectively. Electrorheological (ER) fluids were prepared by dispersing the synthesized PANI-H3PO4 particles in kerosine (including 5wt% of Span 85), and their steady-shear rheological properties under electric fields were investigated using a rotational rheometer with a high-voltage generator. The PANI-H3PO4 synthesized in this study was found to possess typical ER behavior: shear stress increase with applied electric field strengths.
