- Abstract
- The dispersion stability of the Ag nanoparticles with a mixed surfactant of alkylcarboxylates was quantitatively examined, compared with those of the Ag nanoparticles with a single molecule surfactant of alkylcarboxylates. The nanoparticles with a mixed surfactants have far-improved dispersion stability compared with those with normal alkylcarboxylates. The surface roughness of the surfactant layer might be responsible for the improved dispersion stability through the enhanced solvent-surfactant interaction and the decrease in inter-particle surfactant interactions.
