Highly electrically conductive copper power and films were prepared with a polymeric dispersant. The freestanding synthesized CuNPs had a special size patterns distribution and a diameter of approximately 35 nm are fabricated by transmission electronic microscopy. Furthermore, thin films of CuNPs were prepared on a 60 μm thick film that were consistent with a sheet resistance as low as 6.92×10<sup>-2</sup> Ω/sq through surface migration could be prepared by controlling the annealed temperature on ovan at 300 C to form an interconnected network and by using CuNPs/ PTT1-B1 with NaBH<sub>4 </sub>as a reductant. During the heating process, the color of the mixture was changed from blue to reddish, indicating the precipitation of Cu nanoparticles. These nanohybrid films can deliver exceptional electronic properties which can be exploited in a broad range of applications.
