摘要

We thank Dr. Chatterji for his interest and compliments [1] about our paper [2]. Dr. Chatterji mentions the difficulty that he has in "utilising even the standard DLVO methodology". So do we, to the extent that Dr. Chatterji means estimating the electrostatic force by a Poisson-Boltzmann-type approach. As we stated in our paper: ".. ..It (our treatment of the electrostatic force) remains however limited by the continuum mean field framework in which such approaches are anchored. The limitations of mean field theory are particularly apparent on close approach (approx 2-5 nm). Finite size effects of the ions is perhaps the most immediate to come to mind. However, important deviations from continuum theory only appear important for polyvalent ions [5], and this results essentially from ion correlation effects."
