Abstract

Quasi-elastic light scattering of carnauba wax in the liquid phase is obtained in a heterodyne setup, and dynamic processes are analyzed through electrophoresis. Nonspherical polar clusters are found, containing a net electrical charge. An applied square-wave electric field induces drift and rotation of these clusters. These effects are dependent on strength and frequency of the applied electric field. At 373 K and in the low frequency limit the local electric field strength is approximately 70 times the strength of the applied one. This enhancement is believed to be caused by collective orientation of the clusters. The electrophoretic mobility is 1.1 × 10−12 m2/V sec in the high frequency limit and 7.4 × 10−11 m2/V sec in the low frequency limit. The electric dipole moment is 6.3 × 10−16N−1/2 m−1/2 where N is the cluster density/cubic meter and the net charge is about one or two elementary charges.
