Langmuir , 26 14 , Asheesh Kumar, Gaurav Bhattacharjee, B. Moreover, gemini surfactants can form in solution many morphological structures, like spherical, ellipsoidal, rod shape and worm-like micelles as well as vesicles and helical or tubular forms. The unusual self-assembly behaviour of gemini surfactants possesses challenging puzzles to theoretical investigations [ 83 ].

The assessment of the micelle shape is somewhat difficult because it depends not only on the structure of surfactant. The first anionic dimeric salts with two sulphate groups and two alkyl chains have been synthesized by Okahra in [ 49 ]. Bis-quaternization ester derivatives of gemini surfactant. It is the concentration when monomeric molecules of surfactants abruptly assemble into aggregates called micelles [ ] and they are in the balance.

Diffusion coefficients from pulsed gradient spin-echo PGSE NMR experiments reveal that the annulene gemini micelles are similar in size and shape to those of simple monomeric surfactants [ 71 ]. CrossRef Google Scholar The significant influences on geometry and structure of micelles are temperature, concentration, solution condition and ionic strength [ ]. Elongating the hydrocarbon chain makes the molecule more hydrophobic. Conductometry and tensiometry are the most popular and the easiest methods [ 35 ]. This, in turn, is expected to lead to the introduction of innovative, more effective, surfactant-based products in the near future.
