摘要：

Transparent luminescent ZnO embedded PMMA polymer has been synthesized by means of grafting poly(methyl methacrylate) (PMMA) onto the surface of ZnO QDs after g-methacryloxypropyl trimethoxy silane (KH570) modification. The resulting ZnO/PMMA nanocomposites with KH570-modified nanoparticles have better dispersibility and preserve the superior luminescence of ZnO nanoparticles in the nanocomposites. The obtained PMMA/ZnO nanocomposite films show high transparency, high UV-shielding efficiency and improved thermal stability. The obtained nanocomposite was characterized by Fourier transform infrared spectroscopy (FT-IA), transmission electron microscope (TEM), X-ray powder diffraction (XRD), thermogravimetry (TG), ultraviolet-visible (UV-vis) absorption spectroscopy.
