Abstract
Surface tensions and contact angles onto glass and teflon were determi ned using a K12 processor tensiometer about the whole concentration ra nge at 20, 25, 30 and 35-degrees-C. By means of the Gibbs adsorption i sotherm equation the surface excess values were calculated and compare d between surface phase liquid/gaseous and interface solid/liquid. Abo ve it, the free standard wetting enthalpies were discussed.
