摘要： The present invention relates to copper nano-particles having controlled particle size, high monodispersity, and oxidation stability, a method of preparing the copper nano-particles, and a method of forming a copper coating film using the copper nano-particles. The present invention provides a method of preparing copper nano-particles, comprising mixing a copper salt solution with a mixture of a reducing agent and a solvent; where the copper salt solution is added to the mixture at a temperature of 300° C. or less so that the copper salt solution can react with the mixture. It is thus possible to obtain copper nano-particles with controlled particle size and monodispersity by inducing uniform nucleation and nucleus growth through control of the reaction rate and/or the amount of copper ions during synthesis of the copper nano-particles. Moreover, the copper nano-particles of the present invention employ capping organic molecules, which provide oxidation stability by forming a protective dispersant shell around the copper nano-particles.
