采用介电谱法测量了不同吸附水量的沸石电流变液的介电常数，并利用Cole-Cole方程拟合了各体系的介电参数。分散粒子的介电常数随吸附水的增加而增加，而电流变液的介电增量与吸附水无关。结合界面极化与电流变效应的关系，证实了以往的吸附水介电常数机理不适用于沸石电流变液。在分析不同体系弛豫时间的基础上，提出了介电损耗机理来解释吸附水对沸石/油悬浮液电流变行为的积极影响。
Zeolite electrorheological(ER) liquids with different amounts of adsorbed water were measured by dielectric spectroscopy, and the dielectric parameters of every system were fitted by Cole-Cole equation. The permittivity of the dispersed particle was found to increase with adsorbed water increasing, however, the dielectric increment of the ER liquid was independent on the adsorbed water. Considering the relationship between interfacial polarization and ER effect, the previous permittivity mechanism of adsorbed water was confirmed to be unsuitable to zeolite ER liquids. Based on analyzing the relaxation times of different systems, the dielectric loss mechanism was proposed to explain the positive effect of adsorbed water on the ER behavior of zeolite/oil suspension.
