Synthesis, structural studies and optical behavior of methylcellulose/CuO nanomaterials for optoelectronics

The polymer methyelcellouse (MC) is mixed with copper oxide (CuO) to form the MC/CuO composite using the solution casting approach for optoelectronic devices. The X-ray diffraction (XRD) analysis verified the successful preparation of the nanocomposite films. The XRD data reveals that the pristine film’s structural properties are improved after embedding CuO nanoparticles. The effects of CuO on the optical characteristics were examined. The pure MC had dispersion energy of 0.48 eV, while the MC with 3% CuO had 0.17 eV, the MC with 6% CuO had 0.07 eV, and the MC with 9% CuO had 0.03 eV. However, compared to MC, the oscillation energy E₀ modified from 3.86 for MC to 4.03, 4.22, and 4.77 eV, respectively. The optical properties of MC/CuO composites exhibited a notable enhancement compared to pure MC. This study focuses on developing flexible nanocomposite materials exhibiting unique properties that have potential use in high-performance optoelectronic devices.
