Mechanical Property Analysis on Multi-component Liquids by Dielectric Spectroscopy

点击翻译按钮获取中文摘要

Inks contain pigment particles(and other stuffs such as stabilizer) and have low viscosity and small elasticity. Depending on the medium suspending the pigments as well as the type of pigments, vast differences were found for the dielectric property. By analyzing the dielectric properties of the inks, relationship between the polarization and surface tension of the ink, and their contribution to the ink performance was discussed. A dielectric method of characterization could be useful for evaluation of the ink performance in jet printing.
