دراسة التأثير في الخصائص التركيبية الأغشية رقيقة من بولي فينايل الكحول (PVA)‎ المشوبة بخلات الزنك المائية بعد تعريضها للأشعة السينية ثم لحزمة ليزر CO2 وبالعكس

Abstract EN

This research includes the study of the structural properties of the prepared films The research aims to study the effect of each of the irradiation with a carbon dioxide laser beam CO2 And a beam of X-rays, as well as the effect of the doping process on the thin films of a polymer polyvinyl alcohol (PVA) doped with aqueous zinc acetate (Zn (CH3CO2) 2H2O).By weight of 5%, the casting method was used to make it into a thin film It is deposited on glass bases, its dimensions are 25.4*12.5 nm, and its thickness is approximately 380.42 nm.

Then the samples were divided into two parts, the first part was exposed to a CO2 laser beam at a constant energy of 10 Watt and different exposure times (3,6,9,12) sec, then it was exposed to X-rays for 1.5 h, and fixing the voltage of the X-ray machine at a voltage of (5KV).

The second section of the samples were exposed to X-rays for different periods of time (0.5, 1, 1.5, 2, 2.5) h with a voltage of (5 KV).

Then, the samples were exposed to a carbon dioxide (CO2) laser beam with a fixed energy of 10 Watt and a fixed exposure time of 10 sec.

The effect of irradiation in both cases was studied on the optical and structural properties.

The results of X-ray diffraction (XRD) showed that the mixture (PVA + Zn) showed that the crystalline nature of the compounds is amorphous.

For the purpose of studying the topography of the surfaces, the results of atomic force microscopy (AFM) showed a decrease in the particle size after irradiation of the mixture, and it was found that the effect of irradiation is more responsive in the case of (Laser + X-Ray) irradiation than in the case of (X-Ray + laser).
