Nano zinc oxide for UV protection of textiles

International Journal of Technology Transfer and Commercialisation, 2008
This paper describes the effect on the fading of dyed polyester fabrics in artificial sunlight, when the Ultra Violet (UV) component of the radiation was blocked by coating the fabric with zinc oxide nanoparticles, dispersed in an acrylic polymer. Zinc oxide is photoactive and generates superoxide and hydroxyl radicals (Reactive Oxygen Species; ROS ...

Role of surfactants on the stability of nano-zinc oxide dispersions

Particulate Science and Technology, 2015
ABSTRACTNowadays, 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,

Gas sensing performance of nano zinc oxide sensors

AIP Conference Proceedings, 2016
We 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 Research
In 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, 2008
Abstract 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, 2015
Zinc 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, 2014
Polypropylene/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
