n the present study, we report the effect of organic additives and temperature on the micellization of cationic Gemini
surfactants bis- dodecyl dimethyl ethylene diamine (12-2-12). The micellization behavior of Gemini surfactants were studied
at different temperatures at 30
o
C and 50
o
C in different concentrations of organic additives (phenyl propiolic acid) in aqueous
solutions. The micellar environment of aqueous solution of Gemini-organic additives transform into spherical to vesicle
micelles was investigated using nuclear magnetic resonance spectroscopy, rheology, scattering, infrared, microscopic, and
also by dynamic light scattering. Changes in the structural parameters of the micelles with addition of additives were inferred
from SANS measurements. The intensity of scattered neutrons at the low q region was found to increase with increasing PPA
concentration. This suggests an increase in size of the micelles and/or decrease of intermicellar interactions with increasing
salt concentration. Analysis of the SANS data using prolate ellipsoidal structure and Yukawa form of interaction potential
between micelles indicates that addition of additives leads to a decrease in the surface charge of the ellipsoidal micelles and
consequently an increase in their length. The Nagg were confirmed by the SANS and fluorescence measurement.
