초록 | The electrorheological (ER) responses of the polypyrrole(PPy)-coated polyethylene (PE) suspensions in mineral oil were investigated. PPy was coated on PE particles to enhance the particle polarization by increasing the particle surface conductivity, which would lead to the enhanced ER response. The ER response of the PPy-coated PE suspensions is greatly enhanced compared to that of the PE suspension. The dielectric properties of the corresponding suspensions show that the ER enhancement arises from the enhanced particle polarization. Various PPy-coated PE particles were synthesized by controlling the pyrrole or FeCl3·6H20 amount during the pyrrole polymerization, and the ER responses of their suspensions were investigated. The ER response initially increases with the pyrrole or FeCl3·6H20 amount, passes through a maximum, and then decreases with the pyrrole or FeCl3·6H20 amount. |
