Abstract

Theory and controls parameters affecting the output pressure and flow rate of the packed-bed electroosmotic pump (p-EOP), including zeta potential ζ electric intensity E, length of the column L, cross-section area of the column A, dielectric constant ε and viscosity coefficient η of the liquid being pumped, are discussed concisely. And also, the fabrication and application of the p-EOP are introduced.
