摘 要：Copper nanoparticles with a size of about 150 nm were prepared in toluene using oleic acid as protecting agent. The nanoparticles were used to prepare conductive Cu ink with a polyurethane binder. Oleic acid was used to prevent the nanoparticles from oxidization and agglomeration. The prepared Cu nanoparticles were characterized by X-ray diffraction（XRD） and transmission electron microscopy（TEM）. The resistivity of the copper film on glass substrate that was prepared using Cu nanoparticle ink reached about 1.5 × 10-4Ω· cm-1after it was annealed to 120 ℃. Both the nanoparticle ink and the films were characterized by XRD, fourier transform infrared（FT-IR）, and the thermogravimetry-differential scanning calorimetry instrument（TG- DSC）.
