Study of surfactant adsorption on colloidal particles

Abstract

Surface tension and small-angle neutron scattering have been used to study the nature of surfactant adsorption on silica sols. This paper presents results on the characterization of the ludox silica sol and adsorbed layers of hexaethylene glycol monododecyl ether (C12E6). Preliminary results are presented that demonstrate the presence of a lower consolute boundary for the composite system.

Relation between the Variation of the Contact Angle and the Adhesion Force between Silica Surfaces

“…The value of a 1 is about two times less than the value of a 0 . The comparison between a 0 and a 1 indicate that the adsorption of the surfactant at the saturation plateau is attained when a statistical bilayer of surfactant is formed on the silica surface (6,21).…”

Theory and Experiment on the Measurement of Kinetic Rate Constants for Surfactant Exchange at an Air/Water Interface

“…C 12 E 6 at concentrations much less than the CMC (53)(54)(55). Experiments where a given solution is repeatedly exposed to the glass dish of the Wilhelmy plate apparatus, the surface tension measured using the Wilhelmy plate, the solution where g c is the tension of the clean surface.…”

The Effect of Neutral Polymer and Nonionic Surfactant Adsorption on the Electroacoustic Signals of Colloidal Silica

“…Ongoing inthe behavior of model uncharged macromolecules. Two of vestigations into the exact configuration of the surfactant the most commonly studied examples are the linear, flexible molecules and the thickness of each layer continue to be polymers poly(vinyl alcohol), or PVA, and poly(ethylene reported in the literature (34)(35)(36)(37)(38)(39)(40). oxide) (PEO).…”
