PREPARATION AND IDENTIFICATION OF COPPER NANOXIDE USING ZIZIPHUS SPINA-CHRISTI EXTRACT AND STUDY OF ITS EFFECT ON THE PHOTO-PHYSICAL PROPERTIES OF POLY (METHYLMETHA ACRYLATE)

Abstract

Biodegradable polymers have received considerable attention because of their applications in the fields of environmental protection and physical health maintenance. Where the current research was involved, the optical fragmentation study of poly films (Methylmetha acrylate) was prepared by casting method after adding weight ratios of laboratory-prepared nanoparticle oxide from a plant (Ziziphus spina-christi) with weight ratios (0.0025, 0.005, 0.01, 0.02, and 0.04) And at (65 ± 5) micron before and after exposure to the UV source at wavelength. (356) nm and Bazman irradiation (0, 10, 20, 40, 80, and 120) One hour in a row and then follow up on the optical fragmentation process using the UV-visible spectrum device to calculate the dissociation velocity constant (Kd) and an infrared device to calculate the growth coefficient of the carbonyl and hydroxyl groups and viscosity technology to follow the change in the rate of viscous molecular weight. The measured results showed that the decomposition velocity constant was directly proportional to the added copper nanoxide concentration and irradiation time. The growths rate of the carbonyl and hydrologic ejectors of the nanomaterial was diagnosed using modern techniques (AFM, SEM, and XRD). The results showed that copper nanoxide was in the form of irregular spherical particles according to SEM images. The XRD study showed the synthetic properties of the copper nanoxide with a cubic face-centred composition, and the surface topography and minute volume of the nanoxide were studied with atomic force microscope (AFM) technology, which showed that the average minute volume was 20.31 nm
