The influence of Cd(ZnO) on the structure, optical and thermal stabilities of polyvinyl chloride nanocomposites

Abstract

The doping of nanomaterials into polymers creates novel nanocomposite materials with desired properties. The influence of these nanoscale fillers on the structure and optical and thermal stabilities of polymer are the crucial clue to introduce these novel nanocomposites to service life applications. In this work, cadmium doped zinc oxide (Cd 0.5 Zn 0.5 O) nanopowders with a uniform particle size of around 10 nm have been synthesized, purified, and blended with polyvinyl chloride (PVC) by solution mixing to prepare PVC/ Cd 0.5 Zn 0.5 O nanocomposite films. The structure and morphology of PVC/Cd 0.5 Zn 0.5 O nanocomposite films have been characterized using transmission electron microscopy. The results showed that as the amount of nanoscale fillers increases the nanocrystals tend to aggregates and the size of these aggregates increases from 25 to 100 nm. The UV-vis spectra showed that the prepared PVC/Cd 0.5 Zn 0.5 O nanocomposite films are highly transparent. The transparency at higher concentrations slightly decreased as a consequence of light scattering due to large aggregates. The thermogravimetric results showed that a small amount of Cd 0.5 Zn 0.5 O nanopowders (<0.6 wt%) without further surface modification can greatly improve the thermal stability of PVC.

Synthesis, characterization, optical, and dielectric properties of polyvinyl chloride/cadmium oxide nanocomposite films

“…PVC/graphite nanocomposites could be used for attenuation and electromagnetic interference shielding . PVC/(Cd 0.5 Zn 0.5 O) nanocomposites were reported to have high transparency, high UV‐shielding efficiency, and improved thermal stability . PVC/ZnO nanocomposites showed higher glass transition temperature ( T g ), specific heat, and thermal stability relative to those of pure PVC .…”

Dielectric relaxation and optical properties of polyvinyl chloride/lead monoxide nanocomposites

“…Polymer nanocomposites have received much considerable interest during the past few years. Beside the low cost, low density and flexibility, and easy processing, they exhibit good electrical and optical properties. The nano‐additives could improve the overall performances of the polymeric materials, owing to its small size, large specific area, quantum confinement effects and a strong interfacial interaction .…”
