  • Patent number: 9393624
    Abstract: 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.
