Understanding dynamics of colloidal dispersions is important for several
applications ranging from coatings such as paints to growing colloidal crystals for
photonic bandgap materials. The research outlined in this dissertation describes the use
of Monte Carlo and Stokesian Dynamic simulations to model colloidal dispersions, and
the development of theoretical expressions to quantify and predict dynamics of colloidal
dispersions. The emphasis is on accurately modeling conservative, Brownian, and
hydrodynamic forces to model dynamics of colloidal dispersions. In addition, we
develop theoretical expressions for quantifying self-diffusion in colloids interacting via
different particle-particle and particle-wall potentials. Specifically, we have used
simulations to quantitatively explain the observation of anomalous attraction between
like-charged colloids, develop a new criterion for percolation in attractive colloidal
fluids, and validate the use of analytical expressions for quantifying diffusion in
interfacial colloidal fluids. The results of this work contribute to understanding
dynamics in interfacial and bulk colloidal fluids.
