本文对亚微米级乳胶粒子的交流和直流电动特性随粒径、悬浮介质电导率和粘度的变化进行了全面的研究。电泳迁移率和介电泳交叉结果进行了测量，粒径范围从44至2000 nm。的zeta电位的颗粒计算从电泳迁移率数据为不同的悬浮介质的电导率，使用各种模型，有和没有包括表面传导。介电泳数据进行了分析，以获得斯特恩层电导和zeta电位的值。(c)2004爱思唯尔公司All rights reserved.
A comprehensive study of the AC and DC electrokinetic properties of submicrometre latex particles as a function of particle size and suspending medium conductivity and viscosity is presented. Electrophoretic mobility and dielectrophoretic cross-over results were measured for particle diameters ranging from 44 to 2000 nm. The zeta potentials of the particles were calculated from the electrophoretic mobility data for different suspending medium conductivities, using various models, with and without the inclusion of surface conduction. The dielectrophoretic data was analysed to derive values for the Stern layer conductance and zeta potentials. (c) 2004 Elsevier Inc. All rights reserved.
