We describe the method of synthesis of chain-like silver nanowires (nanochains) and
find the favorable conditions to fabricate them. The nanochains are processed in the hot
ethylene glycol solution with constant stirring in the presence of nickel nanoparticles and
polyvinylpyrrolidone 360000 molecules. Silver nanochains consist of straight-linear segments
connected end-to-end. The length of straight-linear segments is from 100 to 500 nm, the
diameter is about 80 nm; the angle between segments varies from 30 to 90°. The total nanochain
lengh reaches 100 microns. The mechanism of silver nanochain formation is discussed.
Keywords: chain-like silver nanowires; silver nanowires; chemical synthesis of nanostructures; metal nanoparticles. |
