A series of novel zinc oxide / Poly (methyl methacrylate) nanocomposite films with different ZnO contents were prepared through inclusion pre-synthesized nanoparticles. The physical composition and morphology the as-prepared nanocomposites studied by XRD TEM. TEM analyses revealed that nanoparticles have a particle size ~3–5 nm. X-ray diffraction proved presence amorphous PMMA in nanocomposites...
