Abstract:
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
