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.
