| SOME monomeric surfactants namely, 3(6- sodium sulfonate hexacyloxy) aniline (MC 6), 3(10- sodium sulfonate decyloxy) aniline (MC10) and 3(12- sodium sulfonate dodecyloxy) aniline (MC12) and their analogous polymers were synthesized. Different techniques were used to characterize the synthesized monomeric and their analogous polymeric surfactants such as ultraviolet-visible (UV), thermal gravimetric analysis (TGA), X-ray and scanning electron microscopy (SEM) techniques. The surface tension technique was used to investigate the surface properties of these surfactants at different temperatures. The critical micelle concentration (CMC) results showed the improvement in the solubility of the synthesized polymeric surfactants according to the effect of the hydrophobic and hydrophilic moieties in their chemical structure. The surface parameters showed the ability of monomeric and their analogous polymeric surfactants for adsorption at the air / water interfaces and decreased the surface tension. The thermodynamic parameters revealed that the micellization process is spontaneous for all investigated surfactants as a result of the improvement of the solubility of these surfactants. | ||
