摘      要：Copper nano-particles were prepared by 100 kGy room temperature γ-ray irradiation of CuSO4 aqueous solution added with surfactant and inactive *** of the surfactants and pH value on particle size and morphology of the Cu powder,and the storage stability,were ***,morphology,particle size and melting point of the copper nano-particles were characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM),laser particle size analyzer and differential scanning calorimetry(DSC),*** results show that the Cu nano-particles prepared with PCM as surfactant and N,N-bis-hydroxyethyl dodecyl amide as inactive agent,in pH=4.0-6.5 of the aqueous solution,can be stored in air for 140 days.
