Comment on 'Drainage of a Thin Liquid Film between Hydrophobic Spheres: Boundary Curvature Effects'

TL;DR

This paper critically examines and corrects fundamental errors in a previous study on the drainage of thin liquid films between hydrophobic spheres, emphasizing the importance of proper boundary curvature considerations.

Contribution

It identifies and rectifies unphysical assumptions in Fang and Mi's 2014 work, providing a clearer understanding of boundary curvature effects in thin film drainage.

Findings

Corrected the boundary curvature assumptions in the previous model

Highlighted the importance of physical consistency in thin film drainage theories

Clarified the impact of boundary curvature on film drainage dynamics

Abstract

We clarify the basic faults in Fang, A.; Mi, Y. Drainage of a Thin Liquid Film between Hydrophobic Spheres: Boundary Curvature Effects. Langmuir 2014, 30, 83-89, which led to unphysical conclusions.
