Abstract:

Copper nano-particles were prepared by 100 kGy room temperature γ-ray irradiation of CuSO4 aqueous solution added with surfactant and inactive agent.Effects of the surfactants and pH value on particle size and morphology of the Cu powder,and the storage stability,were investigated.Structure,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),respectively.The 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.
