Tailored Optoelectronic Materials: DES-Modified MWCNTs in PVA Matrix for Advanced Polymeric Films
Year: 2025
Type: article
Abstract: Integrating optoelectronic functionalities with advanced materials offers exciting potential for novel composite systems. This study investigates the synthesis, characterization, and optoelectronic applications of polyvinyl alcohol (PVA) films incorporating multi-walled carbon nanotubes (MWCNTs) surface-modified with choline chloride-urea (1:2) deep eutectic solvents (DES), known as Reline. Dispersion of Reline-enhanced MWCNT within the PVA matrix is meticulously described. DES-grafted MWCNTs demonstrate improved solubility, leading to superior dispersion within the polymer, confirmed by scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The influence of Reline-grafted MWCNT loading on the films' optoelectronic properties, including optical absorbance, bandgap, and electrical conductivity, is systematically analyzed. Results show that DES-grafted MWCNTs significantly enhance these properties, indicating strong potential for these composites in optoelectronic devices such as solar cells, photovoltaics, photodetectors, and light-emitting devices.
