Abstract:
A series of sulfonate silicone surfactants possessing different hydrophobic groups were synthesized. Their adsorption and thermodynamic parameters in aqueous solutions were investigated by surface tension measurements, conductivity, transmission electron microscopy (TEM) and dynamic light scattering (DLS). These sulfonate-based anionic silicone surfactants exhibit significant surface activity and can reduce the surface tension of water to 19.6 mN m-1 at critical micelle concentration. The TEM and DLS results demonstrate that the three sulfonated silicone surfactants self-assemble into homogeneous sized vesicle-like aggregates in aqueous solution. Moreover, the size of the aggregates was determined to be in the range from 80 to 400 nm at 0.05 mol L-1 .

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...
