Comment on 'Theoretical model of electrode polarization and AC electroosmotic fluid flow in planar electrode arrays'

摘要

Recent experiments have shown that an AC electric field induces steady fluid flow at or near the surfaces of microelectrodes. The flow velocity is a function of frequency and applied voltage and deriving a full theoretical model has proved difficult. Recently in this journal, M. Scott, K. V. I. S. Kaler, and R. Paul (J. Colloid Interface Sci. 238, 449 (2001)) presented a new theoretical model that not only is less comprehensive than previous ones but also is in direct contradiction to established fundamental principles of electrokinetics.
