The formation of wormlike micelle and the following significant changes in rheological properties suffer misunderstanding from both theoretical and fundamental aspects.
Recently, we have introduced a theory for interpreting such important phenomenon which is referred to as critical intermolecular forces (CIF).
The theory has stated that the hydrophobic effect is the main factor for the formation of worm-like aggregates.
Therefore, it seems interesting to check out the validity of this new physical insight through investigating the presence of benzene ring as less hydrophobic group in contrast to that of alkyl in surfactant tail.
The mixture of anionic sodium dodecylbenzenesulphonate (SDBS) and cationic cetyltrimethylammonium bromide (CTAB) shows a high dynamic viscosity peak at the ratio of 80/20 of 3 wt.% CTAB/SDBS indicating the formation of wormlike micelles.
The thermodynamic properties have been evaluated for this mixture exhibiting good agreement with the rheological changes.
Interestingly, the results show the presence of benzene ring (in SDBS) causing a negative effect towards the formation of one dimensional aggregate in contrast to previous results which support the proposed CIF theory.
The presence of nonionic surfactant TritonX-100 in binary and ternary systems of SDBS and CTAB prohibits the formation of wormlike micelles.
