Patent ID: 8491699

Claim:
A method for preparing silver nanoparticles employing ethanolamine, comprising the steps of: (A) reacting ethanolamine, poly(oxyalkylene)-amine, and epoxy at 100° C. to 150° C. for 5 to 10 hours to generate a polymeric polymer, wherein the ethanolamine has a general formula (HOCH 2 CH 2 ) 3-Z N(R) Z , and wherein z=0, 1, or 2, and R=H, alkyl of C1 to C18, or alkenyl of C2 to C18; and (B) reacting the polymeric polymers with silver ions at 15° C. to 35° C. for 12 to 36 hours to reduce the silver ions to silver atoms and disperse the silver atoms as silver nanoparticles (AgNp).
