The oxygen permeation properties of polypropylene nanocomposites were examined to compare their oxygen-barrier performance as affected by temperature (25-50 C), relative humidity (0-50% RH), and nanoparticle contents. Polypropylene/clay, polypropylene/ZnO composites and polypropylene/clay/ZnO ternary nanocomposites were prepared with different compositions by melt compounding to determine the optimum amount of nanoparticles. The results showed that at low temperatures, the effect of both clay and ZnO nanoparticles on oxygen barrier properties of polypropylene was very low. The resulting PP nanocomposites showed increase in oxygen permeability as temperature increased, with an Arrhenius behavior, and activation energy of 43.9-44.7 kJ/mol. The differential scanning calorimetry results indicated that the addition of clay and ZnO nanoparticles in composites slightly decreased melting temperature (T m) and crystallinity (X c %). It was found that ternary nanocomposite prepared by incorporating 5 wt% of nanoclay and surface treated 1 wt% ZnO to polypropylene had the lowest gas permeability and its oxygen permeability was 24.5% lower than that of pristine polypropylene at 50 C.

“…The produced precipitate was collected by centrifugation, filtered using a micrometer filter paper, and then, washed twice with deionized water and three times with ethanol. After washing, the precipitates were placed in an oven at 100°C overnight to be dried and later at 300°C for 2 hours to be calcined (25,26).…”

Background: Volatile organic compounds are the major environmental pollutants causing adverse effects on the human health and the environment, therefore, tremendous effort has been put toward eliminating these compounds. Methods: In this study, the effect of synthesized nanoparticles on the removal of styrene from gas phase by photocatalytic process under UV irradiation in the cylindrical photoreactor was studied. The activated carbon-zinc oxide (AC-ZnO) catalysts were prepared at different weight ratios (6%, 12%, and 18%) of ZnO. The prepared catalyst was characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and Brunauer-Emmett-Teller (BET) analyses. The effects of various parameters, such as concentrations of styrene, various weight percentage (wt%) of nanoparticles, and UV irradiation, were investigated. The efficiency of the AC-ZnO catalyst was determined based on its adsorption capacity, breakthrough time, and removal efficiency. Results: It was revealed that the photocatalytic removal efficiency of styrene was high in the presence of both ZnO nanoparticle and AC under UV light. Under optimal conditions, the efficiency of UV/ACZnO 18%, UV/AC-ZnO 12%, and UV/AC-ZnO 6% catalysts was 77%, 86%, and 83%, respectively. By increasing the concentration of input styrene, the photocatalytic removal efficiency was reduced, while the adsorption capacity of styrene increased. Conclusion: According to the results, the AC-ZnO 12% exhibited higher activity compared to other photocatalysts. Also, the amount of stabilized ZnO nanoparticles on the activated carbon affects the elimination rate of styrene.

“…Sun et al (2011) showed that modified ZnO nanorods is synthesized using gold nanoparticles as additive and thus it is improved the photocatalytic activity. Akin and Oner (2012) obtain by a simple wet chemical method using zinc nitrate hexahydrate and hexamethylenetetramine as the starting materials in the presence of carboxymethyl inulin (CMI). Effect on the morphology, surface area, particle size, and size distribution of zinc oxide has been investigated with changed reaction temperature and CMI concentration.…”

Length, width and specific surface area are among the important criteria representing ZnO crystallization. The average width, average length and surface area of the synthesized ZnO crystals are important because they directly change the application area in which the material will be used. In this study, the factors affecting these criteria were determined as the amount of poly(sodium 4-styrenesulfonate), ultrasonication power, reactant concentration and reaction temperature. The effects of the factors on the selected criteria are analyzed and determined using the Taguchi experimental design method and main effect analysis. The results showed that if the ZnO crystals to be produced are to be used as catalysts, a lower PSSS concentration should be preferred for the synthesis of these crystals, which are smaller in size and have a larger surface area. Another result is; It is seen that the amount of additive and ultrasonication are the two most effective parameters on the average width, average length and specific surface area properties of the synthesized ZnO crystals.
