Optical and Electrical Properties and Thermal Stability of Nanocomposites Containing CuO and ZrO2 Doped into Carboxy Methyl Cellulose for Batteries Applications

The laser ablation technique was utilized to fill the carboxy methyl cellulose (CMC) solution with zirconium dioxide (ZrO2) and copper oxide (CuO) nanoparticles with different concentrations. Different techniques have been used to study the physical behavior of fabricated compositions. CuO has shown different peaks at related to the monoclinic phase of the prepared CuO NPs lattice constants (JCPDS No. 02-1225). According FTIR results, ZrO2 has exhibited vibrating bands at 460 cm(-1), 477 cm(-1), 670 cm(-1), and 690 cm(-1) which are corresponding to Zr-O vibration. In addition, CuO has shown vibrating bands at 439, 494, and 594 cm(-1). The dielectric properties have been investigated. The TGA results showed that the sample CMC-ZrO2-CuO/20 min has excellent thermal stability as the weight loss is 36% of its initial weight at 796 degree celsius. The optical and electrical characterization showed that the addition of ZrO2 and CuO has changed and enhanced the electrical characterization of CMC. The enhancement in electrical conductivity of the system encourages it for electrical applications.
