Abstract
The reversible properties of cluster phases have been
described by theories that invoke Coulomb interactions as a stabilizing
mechanism.What is lacking so far is direct measurement of these charges.
This contribution aims at predicting what to expect if electrophoresis
measurements were to be performed on these systems. As a result, we get
a picture that exhibits several interesting features: (1) The existence of
monomers and clusters lead to distinctly different mobilities (zeta
potentials) in a single sample. (2) Strong dependence of the mobilities
on particle volume fraction. It is our aim that the theory outlined in this
paper may serve as a guideline to interpret the expectedly “messy”
electrophoretic measurements.
