Reversible adsorption kinetics of near surface dimer colloids Paul F. Salipante* and Steven D. Hudson National Institute of Standards and Technology, Polymers and Complex Fluids Group, Gaithersburg, MD
Abstract
NIST Author Manuscript
We investigate the effect of shape on reversible adsorption kinetics using colloidal polystyrene dimers near a solid glass surface as a model system. The interaction between colloid and wall is tuned using electrostatic, depletion, and gravity forces to produce a double well potential. The dwell times in each of the potential wells is measured from long duration particle trajectories. The height of each monomer relative to the glass surface is measured to a resolution of
