Reaction Conditions

Reaction Steps

In a reaction vessel, deionized water, 10% solution of dodecyl thiopolyacrylamide (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 the speed of adding. The content in the reaction vessel was maintained at the reaction temperature for 30 minutes, cooled to room temperature, and decanted, so that a nanoparticle silver behenate dispersion was obtained (solid content 3%) with median grain size of 150 nm.
