Work of adhesion and activity of aqueous solutions of ternary mixtures of hydrocarbon and fluorocarbon nonionic surfactants at the water-air and polymer-water interfaces

Comparison of the values of the activity at the PTFE-water interface (aS,SLS) of aqueous solutions of the ternary surfactant mixtures composed of TX100, TX165 and FSN100 at the total concentration in the bulk phase equal to 10−4 M, calculated on the assumption that γSV for PTFE is equal to 20.24 mN/m, and that γSV is not constant and is equal to that determined for FSN100 at a given concentration.
