المستخلص

PVC/PS (polyvinyl chloride/polystyrene) polymer blend embedded copper chloride (CuCl2) with
different wt.% were synthesized using the casting method solution technique. The prepared
composite films were described by appropriate techniques such as X-ray diffraction and UVvisible
spectrum. The amorphous nature of the structure for the composites was confirmed by
X-ray spectra. In the UV/Vis. spectrum of PVC/PS showed CUT-OFF range that was largely
increased after the filler addition, where there is a significant decrease in the transmittance values
of filled films from 80% for pure PVC/PS blend to 1% for the sample (8 wt% CuCl2). This result
mean that, the prepared composite film can be used as a promising material for excellent UV–
Vis optical limiting and UV-protector. Add to that, doping PVC/PS polymeric blend with
different concentration of CuCl2 leads to a strong decrease in the band gap from 4.38 eV for
PVC/PS polymeric blend till it becomes very close to 2.61 eV for PVC/PS - 8 wt % CuCl2 .
