Abstract

The dynamic foam behaviour of anionic, cationic, and non-ionic surfactants with and without nanoparticles (NP’s) were investigated. Effect of titanium dioxide (TiO2) and silicon dioxide (SiO2) NP’s on foam stability of sodium lauryl sulfate (SLS), cetyl trimethyl ammonium bromide (CTAB) and tween-80 (T-80) surfactants were studied. Foam stability was determined by measuring the half-life time (t1/2) and normalized foam height (NFH). NP’s were attached to the curved foam surfaces and helps to enhance the foam stability. The dynamic foam behaviour of the surfactant solution in the presence of NP’s was characterized by transmission electron microscope (TEM), zeta potential value. Results revealed that the more stabilized foam was observed in the presence of NP’s. SiO2 NP’s gave more foam stability as compared to TiO2 NP’s. Axial dye displacement through foam section was studied in the presence and absence of NP’s.
