Abstract
Mono-, di-, triethanolamine in a combination with methylmorpholinium and hydroxyethylmorpholinium surfactants were investigated for their aggregation and solubilizing properties. A cooperative behavior of the solubilization by mixed surfactant – ethanolamine systems is described. Ethanolamines strongly affect pH and lead to Orange OT phenolic group deprotonation and subsequent increase in aqueous/micellar solubility. The morpholinium surfactant micelles reduce pKa of Orange OT phenolic group, enabling its deprotonation at the earlier stages of media alkalinization. Obtained surfactant – ethanolamine mixtures can solubilize very large amounts of hydrophobic dye, which can then be triggered to precipitate via acidification.

期刊介绍：
The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace.
Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
