Reaction Conditions

Reaction Steps

In a reaction vessel, deionized water, 10% solution of dodecyl thiopolyacrylamide surfactant (72 g) and 46.6 g of recrystallized behenic acid were placed. The content in the reaction vessel was heated at 70° C. with stirring at 150 rpm, while 10% potassium hydroxide solution (70.6 g) was added to the vessel. Thereafter, the content in the reaction vessel was heated at 80° C., and maintained at the same temperature for 30 minutes until the content became a turbid solution. Next, the reaction mixture was cooled to 70° C., and a silver nitrate solution (100% solution, 21.3 g) was added to the reaction vessel over 30 minutes by controlling adding speed. The content in the reaction vessel was maintained at the reaction temperature, cooled to room temperature, and decanted, so that a nanoparticle silver behenate dispersion having a 150 nm nedian grain size was obtained (solid content 3%).
