Title: Microrheology of colloidal dispersion. Part 13. Trajectories of orthokinetic pair collisions of latex spheres in a cationic polyelectrolyte

Abstract

A previous study dealt with shear-induced (or orthokinetic) collisions of colloidal-size latex spheres in aqueous glycerol solutions of electrolyte, and described a method of analyzing the particle trajectories using hydrodynamic theory in conjunction with the DLVO theory of colloid stability. This work extends the observations and trajectory analysis to the case where a cationic polyelectrolyte has been adsorbed on the latex spheres. The trajectories of colliding 2.6- and 4.0-micrometer diameter polystyrene latex spheres in aqueous glycerol containing KCl undergoing poiseuille flow were observed in the presence of a cationic electrolyte, cat-floc, adsorbed on the latex. 25 references.
