Dynamic surface tensions and dynamic surface potentials of aqueous solutions of a cationic surface active electrolyte

A disjoining pressure study of foam films stabilized by mixtures of a nonionic (C12DMPO) and an ionic surfactant (C12TAB)

“…Dodecyl trimethylammonium bromide (C 12 TAB) is also seen as a good candidate for a fundamental study as it is cheap and can be easily purified. Furthermore, there exists a vast amount of work on the adsorption of C 12 TAB at the water-air interface, namely studies of dynamic [32][33][34][35] and static [10,[36][37][38][39][40] surface tensions, surface elasticity [34,41,42], foam films [10,38,39] and foams [39,43].…”

Adsorption of alkyl trimethylammonium bromides at the air/water interface

“…The equilibrium surface tension of aqueous C n TAB solutions for n = 10, 12, 14, and 16 was studied in Refs. [1][2][3][4][5], while in other studies [6][7][8][9] the dynamic surface tensions and adsorption in the short time range (oscillating jet and inclined plate methods) were presented, and the adsorption mechanism of C n TAB was analysed. In addition, extensive neutron reflectivity studies were published [3,[10][11][12][13].…”

Measurements of the Adsorption Kinetics of a Cationic Surfactant in a Liquid Jet by Ellipsometry

“…Any relaxation of the surface dipole contribution would reduce the surface potential and hence the apparent surface concentration obtained from the surface potential method. Joos and co-workers have postulated a cooperative dipole relaxation process 5 to explain their data on alcohols, Triton surfactants, and the 14-carbon homologue of CTAB, tetradecyltrimethylammonium bromide (MTAB) …”
