Abstract:
1. A production apparatus of composite silver nanoparticle comprising a raw material mixer for preparing an alcohol solution by mixing of a silver salt microparticle into at least an alcohol solvent added more excessively than the mol number of said silver salt microparticle so as to become an excess alcohol solution, wherein said alcohol solvent selected from alcohols with a carbon number of 1 to 12 composed of methanol, ethanol, propanol, butanol, pentanol, hexanol, heptanol, octanol, nonanol, decanol, undecanol and dodecanol, a reactor for generating a composite silver nanoparticle by heating said excess alcohol solution at a generation temperature PT generating an aldehyde for a generation time with a heater, in which a silver core is formed through reducing of said silver salt microparticle by said alcohol solvent and/or said aldehyde and said composite silver nanoparticle having an organic coating layer originated from said alcohol solvent around said silver core is formed, a chiller for cooling said alcohol solution; and a component purifier separating said composite silver nanoparticle from said alcohol solution, wherein said component purifier is composed of a centrifugal ultrafilter and said composite silver nanoparticle is diffused into an extraction solvent through a pore so that a purified liquid is formed.
