PREPARATION METHOD OF SILVER NANOWIRES

摘要

A preparation method of silver nanowires is provided. First, droplets of an ethylene glycol solution of silver nitrate is atomized by ultra-sonication and then added into a heated solution containing polyvinylpyrrolidone and sodium chloride to form silver nanowires. Comparing with the method without the ultra-sonication, the above method can increase the yield and the aspect ratio of the silver nanowires.

主权项

1. A method of preparing silver nanowires, the method comprising:
respectively preparing ethylene glycol solutions of polyvinylpyrrolidone (PVP), sodium chloride (NaCl), and silver nitrate (AgNO3); heating the glycerol solution of PVP to a temperature of 155-165° C., wherein the temperature is maintained; adding the glycerol solution of NaCl into the heated glycerol solution of PVP to form a mixture solution; atomizing droplets of the glycerol solution of AgNO3 to form atomized droplets in micronmeter's scale; adding the atomized droplets into the mixture solution to form a reaction solution and to form a plurality of silver nanowires; cooling the reaction solution; and purifying the silver nanowires.
