Critical adsorption on nonspherical colloidal particles

J Chem Phys. 2007 May 7;126(17):174902. doi: 10.1063/1.2723070.

Abstract

We consider a nonspherical colloidal particle immersed in a fluid close to its critical point. The temperature dependence of the corresponding order parameter profile is calculated explicitly. We perform a systematic expansion of the order parameter profile in powers of the local curvatures of the surface of the colloidal particle. This curvature expansion reduces to the short distance expansion of the order parameter profile in the case that the solvent is at the critical composition.
