Green chemistry mediated synthesis of cadmium sulphide/polyvinyl alcohol nanocomposites: Assessment of microstructural, thermal, and dielectric properties

Popis výsledku v původním jazyce

In the present study, a green synthesis approach has been employed to prepare cadmium sulphide nanoparticles (CdS NPs). The prepared CdS NPs were used as nanofiller (0-3 wt%) to produce polyvinyl alcohol (PVA)/CdS nanocomposite films via solution casting technique. The Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, and atomic force microscopy were employed to investigate various properties of PVA/CdS nanocomposite films. An enhancement in the structural, thermal, and morphological properties of the PVA/CdS nanocomposite films was noticed confirming the successful incorporation of CdS NPs in the PVA matrix and good interaction between the polymer and the nanofiller. Further, an impedance analyzer was employed to evaluate dielectric properties of the PVA/CdS nanocomposite films at various frequencies (50 Hz-1 MHz) and temperatures (40C-140C). The dielectric constant (ε) and dielectric loss (tanδ) values of PVA/CdS nanocomposite films loaded with 3 wt% of CdS NPs were found to be 423.71 and 4.18, respectively, at 50 Hz and at 140C. An improvement in the dielectric properties evidenced the homogeneous distribution of CdS NPs within the PVA matrix making the nanocomposite films useful for electrical charge storage devices.
