摘要：

Composites of nanocrystalline iron disulfide (FeS2) coated with poly(vinyl pyrrolidone) (PVP) or poly(vinyl alcohol) (PVA) have been successfully synthesized using a solvothermal process, in which PVP and PVA serve as soft templates. Transparent, flexible thin films of these nanocomposites were prepared from homogeneous solution using a solution-casting approach. X-ray diffraction and thermogravimetric analysis and energy-dispersive X-ray, Fourier transform infrared and UV-visible absorption spectroscopic techniques were employed to study the structural and optical properties of these nanocomposite films. UV-visible spectra in transmission mode reveal the UV-shielding efficiency of these nanocomposite films and the films are found to be exceptionally good for UV-shielding applications in the wavelength range 200 to 400 nm. The present work aims at developing transparent and flexible UV-shielding materials and colour filters using cost-effective and non-toxic inorganicpolymer nanocomposites.
