Abstract

We study the scaling of adsorption isotherms of polyacrylic dispersants on generic surfaces of metallic oxides \(XnOm\) as a function of the number of monomeric units, using Electrostatic Dissipative Particle Dynamics simulations. The simulations show how the scaling properties in these systems emerge and how the isotherms re-scale to a universal curve, reproducing reported experimental results. The critical exponent for these systems is also obtained, in perfect agreement with the scaling theory of de Gennes. Some important applications are mentioned.
