Abstract In order to obtain efficient electrophoretic inks, Tridodecylamine (Dod3N), has been studied as charge control agent (CCA) in a non-polar paraffin solvent (Isopar G) for various inorganic pigments (TiO2 and Fe2O3). All hydrophobic mineral oxides, i.e. treated with octyltrimethoxysilane (C8) or dodecyltrimethoxysilane (C12), were found to be negatively charged in presence of Dod3N. The electrophoretic mobilities of inorganic pigments seemed to be strongly dependent of their isoelectric point (IEP) and also of the concentration of dod3N with an optimum range between 10 and 20 mM depending on the pigments. Finally, an electrophoretic ink constituted of hydrophobic mineral oxides in presence of Dod3N was tested in a device. Its efficiency as charge control agent to negatively charge hydrophobic particles was confirmed through good optical properties and fast response time (220 ms at 200 kV m−1).

Tridodecylamine，一种用于电泳油墨应用的非极性介质中的有效电荷控制剂

摘要 为了获得高效的电泳油墨，研究了十三烷基胺 (Dod3N) 在非极性石蜡溶剂 (Isopar G) 中作为各种无机颜料 (TiO2 和 Fe2O3) 的电荷控制剂 (CCA)。发现所有疏水无机氧化物，即用辛基三甲氧基硅烷(C8)或十二烷基三甲氧基硅烷(C12)处理的，在Dod3N存在下都带负电荷。无机颜料的电泳迁移率似乎强烈依赖于它们的等电点 (IEP) 和 dod3N 的浓度，最佳范围在 10 到 20 mM 之间，具体取决于颜料。最后，在装置中测试了在 Dod3N 存在下由疏水性矿物氧化物构成的电泳墨水。
