Silver hydrosol, organosol, and reverse micelle-stabilized sol : A comparative study

Abstract Surfactant-stabilized silver hydrosol, organosol, reverse micelle-stabilized sol, and their dry products have been prepared and characterized. The dry products can be handled as chemical compounds. Solubility and spectral study of dry products show similar microenvironments for the organo- and reverse-micellized sol. For the conversion of hydrosol into organosol, the surfactant acts as phase transfer catalyst. The study shows that a solvent–surfactant system for which the surfactant can form a reverse micelle is effective for phase transfer of particles from aqueous to organic phase.
