Preparation and (TiO2-ZnO) Polyethelene for Food Preservation

Abstract

Abstract The polymer nanocomposite was prepared using low-density polyethylene and each of (titanium oxide and zinc oxide) nanoparticles by casting method. The nanoparticles were synthesized via the UV-irradiation method. structural properties of TiO2 and ZnO nanoparticles studied by x-ray diffractions so the grain size of nanoparticles ranged between (10-12) nm. mechanical properties of the nanocomposites improve as the ratio of nanoparticles in polymer increased, compared to pure LDPE. Given that studies show that using this 2.5 Gy of gamma Rayes irradiated of nanocomposites improved that fantastic for use as food packaging. Besides, the polymer nanocomposites proved that antimicrobial properties against the E. coli, since it releases the nanoparticle’s cations.
