Abstract

The possibility of using specular neutron reflectometry to study aqueous trisiloxane solutions during the transition to the superwetting state was shown. The adsorption of trisiloxane surfactants from solution onto a moderately hydrophobic surface (oxidized titanium film) with increasing temperature up to the cloud point of the solution was considered. To clarify the role of the hydrophobic part of trisiloxane surfactant molecules in the superwetting effect, a comparison was made with solutions of a nonionic hydrocarbon surfactant with similar polyoxyethylene chains.

Keywords

solutions of surfactants, superwetting agents, neutron reflectometry.
