Cu/CuO Composites films have been developed at different concentration of copper acetate with0. 3M, 0.35M, 0.4M and 0.45M at 300C by spray pyrolysis technique and the effect of concentration on the structural, surface and electrical properties of the films have been investigated. The crystalline structure of the prepared films has been studied using X-ray diffractometer (XRD). The XRD patterns confirmed the presence of cubic structure of Cu and CuO in the films in a reduced atmosphere created by NHOH and ethanol. The surface properties have been characterized using Scanning Electron Microscopy (SEM). The surface of the as-deposited films is smooth and comprised of uniformly distributed grains. The resistivity has been investigated by Four probe method for different molar concentrations of copper acetate. The resistivity for the film deposited with the optimized concentration of 0.4M is found to be 4.34X10-02cm. From the study it is evident that molar concentration of copper acetate has a strong effect on the structural, surface and electrical properties of Cu/CuO composite films and an optimum molar concentration has been fixed.
