Abstract

CuO@Alginate (CuO@Alg) nanocomposite has been synthesized by simple, inexpensive and highly efficient Sol-Gel method. The morphology and structural properties of synthesized nanocomposite (CuO@Alg) and pure CuO nanoparticles have been analyzed as a function of temperature. The morphological and structural properties were investigated by using TEM, SEM, EDX, and X-ray diffraction. The crystalline nature of CuO nanocomposite showed by X-ray diffraction (XRD) pattern and average crystalline size was observed approximately 18.09 nm. The effect of size quantization on morphology was also observed. Dielectric behavior of CuO and CuO@Alg has been also studied as a function of increasing frequency by LCR meter. With the increase in frequency, the dielectric constant was found to decrease and alternative current (A.C.) conductivity value was found to increase. This study was also representing a useful step towards the establishment of a structure–property relationship for CuO nanocomposite.
