Abstract
Enhancing of the properties of low density polyethylene (LDPE) by the addition of inorganic fillerin
addition to a novel method to synthesis zinc peroxide (ZnO2) nanoparticles are the main objectives
of this study.
Inorganic nanocomposites were prepared by cast solutionof LDPE with different amounts
of ZnO2 nanoparticles: 0%, 1%, 1.5%, 3%, and 5% by weight. Thermal, chemical, morphological,
and tensile properties were investigated, respectively, using differential scanning calorimetry
(DSC), Fourier-transform infrared spectroscopy (FTIR), X-Ray Diffraction (XRD), scanning
electron microscopy (SEM), and a universal testing machine. The characteristics of the antibiotics
were also evaluated using an antibiotic sensitivity test.
ZnO2 nanoparticles improve melting and cooling points as well as the crystallization
degree. These results are consistent with the assumption that inorganic additives act as nucleating
agents. Additionally, the SEM images demonstrated good filler dispersion within the polyethylene
matrix.Tensile testing showed that the incorporation of ZnO2improves the elastic modulus, tensile
strength and fracture strength while elongation at breakwas decreases. The antibacterial properties
study showed poor activity of LDPE/ZnO2nanocomposites against all types of aerobic and
anaerobic of bacteria studied.
Highly pure crystalline cubic-ZnO2 nanoparticles grown in a near- spherical shape were
obtained with a novel method with average size of 82 nm based on SEM and XRD analysis and a
decomposition temperature about 238oC found by DSC
