Equilibrium adsorption and self-assembly of patchy colloids in microchannels

Abstract

A new theory is developed to describe the equilibrium adsorption and self-assembly of patchy colloids in microchannels. The adsorption theory is developed in classical density functional theory, with the adsorbed phase and fluid phase modeled using thermodynamic perturbation theory. In this work we propose that the introduction of patches on the colloids greatly enhances the temperature dependent and reversible adsorption of colloids in microchannels. It is shown how bulk fluid density, patch size, temperature and channel diameter can be manipulated to achieve the adsorption and self-assembly of patchy colloids in microchannels.
