<p>We recently introduced a straightforward method for determining the Hamaker constant for liquids using their Hansen solubility parameters. Our method is based on the relationship between the surface tension and the Hansen solubility parameters for liquids, as derived by Abbott, and the relationship between the surface tension and the Hamaker constant for liquids, as established by Israelachvili and revised by David and Neumann. In this paper, we demonstrate that this method is also applicable to polymers. For polymers, we use Murase and Nakamura’s formula for the surface tension/Hansen solubility parameter relationship in place of Abbott’s formula, along with Israelachvili’s formula for the corresponding surface tension/Hamaker constant relationship. Our approach for determining the Hamaker constant of polymers using their Hansen solubility parameters is shown to be generally valid for a wide range of polymers.</p> Graphical Abstract <p></p>
