Wettability, adhesion, adsorption and interface tension in the polymer/surfactant aqueous solution system. I. Critical surface tension of polymer wetting and its surface tension

► The critical surface tension of polymers wetting by the surfactant solution is different from their surface tension. ► For PMMA and nylon 6 the linear dependence between the adhesion and surface tension depends on the surfactant type. ► The interaction parameter is not a linear function of the polymer-surfactant solution interface tension.
