Abstract

Based on the adhesion tension isotherms γLVcosθ = fLV), the relationship between the adsorption values of surfactants at the solution/solid surface (ГSL) and solution/air (ГLV) interfaces was examined by wetting Teflon and polystyrene with aqueous solutions of the nonionic surfactant Triton X-100 (TX-100). The approach presented in this paper demonstrates the feasibility of predicting the wettability of hydrophobic surfaces for practical applications, using an existing database on the surface tension of aqueous surfactant solutions and their adsorption on the surface of solid adsorbents.
