Abstract
A series of novel zinc oxide / Poly (methyl methacrylate) nanocomposite films with different ZnO contents were prepared through inclusion of pre-synthesized zinc oxide nanoparticles. The physical composition and morphology of the as-prepared nanocomposites were studied by XRD and TEM. The TEM analyses revealed that the zinc oxide nanoparticles have a particle size of ~3–5 nm. X-ray diffraction proved the presence of the amorphous PMMA in the nanocomposites. The intermolecular interactions within the polymer nanocomposites were explored by FTIR and XRD. FTIR spectra confirmed the dispersion of the zinc oxide nanoparticles in the Poly (methyl methacrylate) i.e. PMMA matrices. The UV-Vis absorption measurements of the ZnO/PMMA nanocomposites proved their potential optical properties.
Highlights
The dispersal of nanosized inorganic fillers into polymer medium to form polymer nanocomposites has drawn vast interest in current years [1]
We effectively introduced previously synthesized consistent and fine quantum-size zinc oxide nanoparticles into a PMMA polymer matrix to prepare a series of steady ZnO/PMMA nanocomposite films with three dissimilar concentrations
Strong absorbance in the UV region and small absorbance at the visible region, that means a typical optical property of the combination of visual transparency and UV filters closed to the visible wavelength which was observed for the nanocomposite films
Summary
The dispersal of nanosized inorganic fillers into polymer medium to form polymer nanocomposites has drawn vast interest in current years [1]. PMMA (Polymethyl methacrylate) has been a popular choice for the preparation of polymer-inorganic composites and is selected as a supporting matrix in the current study because it is striking due to its light weight, smoothness, flexibility, environmental durability, high clearness, light transmission, milder processing conditions and biocompatibility. Besides it is a versatile polymeric material extensively used to make windows, eye contact & camera lenses along with other optical apparatus & many imaging and non-imaging microelectronic applications [4, 9]. ZnO nanoparticles and the ZnO/PMMA nanocomposites were characterized by using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), and UV-visible spectroscopy
