DC conductivity studies of CuO Nano petals incorporated PMMA Thin Films

CuO nano petals are synthesised by the chemical precipitation method. XRD, SEM, and TEM are used to accomplish structural and morphological studies. Based on XRD results, the average grain size is calculated to be 12 nm, and the structure of nanoparticles is identified as Monoclinic. SEM and TEM analyses confirm that the synthesised nanostructure exhibits a nano petal morphology. The optical properties are characterised using UV-vis DRS Spectrophotometer, and the band gap is determined to be 1.3 eV. Three samples of PMMA, each with varying concentrations of CuO (10%, 20% and 30% nano petals) are spin-coated onto pre-cleaned FTO-coated glass substrates. The current-voltage characteristics of the annealed film are studied by the two-point probe method. The film with 10% CuO exhibited better D.C conductivity than the other concentrations.
