  • Abstract

    To understand the role of molecular architecture of surfactant molecule on micellar structure, a series of cationic surfactants was taken viz. cetyl trimethyl ammonium bromide (CTAB-1), cetyl hydroxyethyldimethyl ammonium bromide (CTAB-2) and cetyl dihydroxyethyl methyl ammonium bromide (CTAB-3) has been investigated by small angle neuron scattering measurement. Critical micelle concentration, Kraft temperature for a series of surfactant was determined by conductance measurement, where as aggregation number, effective fractional charge per monomer, equilibrium distance between the charged heads and dimension of micelle were determined from small angle neutron scattering data. It is observed that the number density of micelle and dimension of micelle were observed to increase and hence oil solubilization of surfactant system was also observed to increase from CTAB-1 to CTAB-2 and then CTAB-3.
