Structural properties of confined colloidal suspensions Conference Paper uri icon

abstract

  • The study of colloidal suspensions under conditions of severe confinement is a topic of considerable current interest. This is due to the practical importance of such systems, and to the many fundamental questions that these systems present to the field of colloid physics. A review of basic concepts of colloidal physics such as interparticle interaction, stability, static and dynamic structures are discussed. The experimental procedures of system preparation, measurement and analysis of those properties in quasi-two-dimensional colloidal is presented. The experimental systems consist of aqueous suspensions of latex particles in the micrometer range, confined between to glass plates. Digital video microscopy is used to determine different quantities of interest such as the pair correlation function, the dynamic structure factor, the mean squared displacement, and the hydrodynamic diffusion coefficients. © 2007 American Institute of Physics.
