Abstract: We have studied the effect of low dose gamma irradiation on CuO have been prepared by sol gel method and the Polyaniline (PANI) - CuO composites can be synthesized by the method of polymerization. The obtained CuO and PANI-CuO composite powders were irradiated with energetic gamma ray of dose rate 11 Gray per minute at room temperature. The radiation induced changes in the structural, morphological and optical properties of CuO and polymer composite were analyzed with X-ray diffraction (XRD), Scanning electron microscope (SEM), Ultra violet -Visible spectroscope (UV-Vis), and Fourier transform infrared spectroscope (FT-IR). The XRD spectrum shows that the crystalline nature of sample is still present after irradiation and the corresponding 2θ values are shifted to higher side and the particle size will be increased. The morphological changes due to the gamma irradiation were confirmed by SEM images. The UV absorption spectra revealed the absorption edge and the corresponding band gap values were correlated. The FTIR spectrum shows the vibrational modes are changing as a result of irradiation.
