Role of surfactants on the stability of nano-zinc oxide dispersions
Particulate Science and Technology, 2015ABSTRACTNowadays, stable colloidal dispersions with ultra-fine or nanosized particles are getting importance due to their higher activity. In this article, methods for the preparation of stable aqueous dispersions of zinc oxide (ZnO) were discussed. The quality of the dispersion was improved by capping with different types of surfactants say non-ionic,

Preparation and Use of Nano Zinc Oxide in Neoprene Rubber
International Journal of Polymeric Materials, 2008Zinc oxide (ZnO) of nanometer particle size was prepared by solid-state pyrolytic method. TEM, XRD, and surface area studies showed that the prepared zinc oxide had particle size in the range of 15–30 nm and surface area in the range of 12–30 m2/g. This nano zinc oxide was used as a curing agent in neoprene rubber.

Gas sensing performance of nano zinc oxide sensors
AIP Conference Proceedings, 2016We report nano Zinc Oxide (ZnO) synthesized by sol-gel method possessing the crystallite size which varies from 25.17 nm to 47.27 nm. The Scanning electron microscope (SEM) image confirms the uniform distribution of nanograins with high porosity. The Energy dispersion X-ray (EDAX) spectrum gives the atomic composition of Zn and O in ZnO powders and ...

The Application of Nano-zinc oxide in Petrochemical
Advances in Engineering Technology ResearchIn today’s world, fossil fuels dominate the energy supply. However, petroleum refining produces many toxic gases, including sulfur oxides, which have caused many serious environmental and health problems. To reduce this negative externality, petroleum firms use desulfurizers to absorb the sulfur.

Characteristics of nano zinc oxide synthesized under ultrasonic condition
Journal of Physics and Chemistry of Solids, 2008Abstract Hydrothermal method is employed to synthesize nano ZnO particles in solutions containing different surfactant at room temperature and 50 °C under ultrasonic condition. The reactants used are aqueous solutions of zinc chloride and potassium hydroxide, and the surfactants are cetyltrimethylammonium bromide (CTAB) and triethanolamine (TEA ...

Formulation of nano-zinc oxide into biocomposite beads for dye decolorization
AIP Conference Proceedings, 2015Zinc oxide nano-powder was prepared using sol-gel technique to be encapsulated onto polymeric blend composed from alginate and polyvinyl alcohol to fabricate novel bio-composite beads of nano-zinc oxide. The XRD patterns of both zinc oxide nano-powder and its polymeric hybrid were crystalline in their nature.

Resistance to Thermal Degradation of Polypropylene in Presence of Nano Zinc Oxide
Progress in Rubber, Plastics and Recycling Technology, 2014Polypropylene/zinc oxide composites were prepared using melt mixing method and made into sheets using compression moulding. 0–5 wt% of zinc oxide (ZnO) with different crystallite sizes were incorporated into the polypropylene (PP). Mechanical properties of the PP were increased by the addition of ZnO. Morphology of the composites showed good dispersion
