REPARAT ION of nano metal oxides (Fe2O3, ZnO and T iO2) and nano …… sphere polystyrene (PS) has been done in micellar solution.Nanocomposite films have been prepared by doping nano polystyrene with different ratios of nano metal oxide ranged from 0.25 up to 3 wt%.T hese nanocomposites were characterized using transmission electron microscopy (T EM), X-ray diffraction (XRD) and Fourier transform in...
