Effect of C12EOn mixed surfactant systems on the formation of viscoelastic worm-like micellar solutions in sucrose alkanoate– and CTAB–water systems

Formation of wormlike micelle in a mixed amino-acid based anionic surfactant and cationic surfactant systems

“…The continuous increase of the plateau modulus G 0 with CTAB can be taken as an evidence of one dimensional micellar growth and hence an increase in the entanglement degree of wormlike micelles. How- ever, the maxima observed in the τ R curve imply some structural changes occur that allows a faster stress relaxation [42].…”

Viscoelastic micellar water/CTAB/NaNO3 solutions: Rheology, SANS and cryo-TEM analysis

“…It is well known that in aqueous solutions of cationic surfactants, for example, hexadecyltrimethylammonium bromide (CTAB), long wormlike micelles form upon addition of some salts, strongly binding counterions or cosurfactants [3][4][5][6][7][8][9][10][11], or upon mixing with anionic surfactants [12,13]. The one-dimensional micellar growth in such systems is attributed to screening of head-head repulsion between amphiphiles, thereby reducing the interfacial curvature of the aggregates.…”

Wormlike micelles in poly(oxyethylene) surfactant solution: Growth control through hydrophilic-group size variation

“…Thus, these systems are very interesting from scientific and industrial standpoints. Therefore a large amount of research employing different materials and various techniques (such as rheology, cryo-TEM, light scattering, small-angle X-ray, and neutron scattering) has been carried out to characterize these systems [2,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. However, most of the past and recent work is focused on ionic surfactant systems [20][21][22][23][24][25].…”
