The influence of component’s chemical nature on wetting effect of mixed surfactant solutionS

Abstract

Wetting of low-energy solids (Teflon, hydrophobized glass) by aqueous binary mixed solutions of different nature surfactants (cationic-anionic, anionic-nonionic) was investigated. The non-additive effect of wetting was founded. It was showed, that one’s magnitude and displaying conditions depend on extent of excessive (compared to the same molecules or ions) attraction of molecules (ions) of components in mixed adsorption layers at the interfaces during the wetting. It was established that reinforcement of mixture’s wetting efficiency might be predicted on the base of surface tension measurements of corresponding solutions.
