Effect of gamma irradiation on the physical and chemical properties of copper-poly vinyl pyrolidone composite films

الملخص EN

Polymer composite films based on poly-vinylpyrrolidone (PYP) doped with different copper concentrations in 1 HNO} were prepared using the solution cast technique.

The polymer films were subjected to “Co y-ray source at various doses ranging between 100 and 400 kGy.

The effect of Cu ions concentration and y-irradiation doses on the physico-chemical properties have been investigated.

FITR spectra gave information about vibration changes that occurred due to copper dopant and y-irTadiation doses.

XRD results indicated that the amorphous domain of the PAT polymer matrix was increased with increasing of the dopant concentration.

The surface morphology was examined (SEM).

The electrical conductivity was increased with the increase of the Cn dopant concentration and y-irTadiation dose.

The direct and indirect optical band gap values were decreased to 3.09 and 2.84 eV respectively as the irradiation dose wad increased to 400 kGy.
