The Bulk and Interfacial
Properties of Aqueous Binary Mixed Solutions of Pluronic L61 with Low-Molecular
Surfactants
Abstract
The bulk and interfacial
properties of polymer non-ionic surfactant pluronic L61 with single surfactants
of different type (ionic, non-ionic) – surface tension, micellization, wetting
and modifying action on hydrophilic and hydrophobic solids – were investigated. In the low concentration
range the synergistic effect of surface tension decrease and wetting action
increase was discovered. Extend of effect’s displaying depends on the type of
single surfactant and mole ratio of components in mixture. It was showed that
the wetting behaviour of hydrophobic solids can be predicted by surface tension
isotherms analysis.
