Majid Montazer, Morteza Maali Amiri and Reza Mohammad Ali Malek In Situ Synthesis and Characterization of Nano ZnO on Wool: Influence of Nano Photo Reactor on Wool Properties Photochemistry and Photobiology 89
The main purpose of this work was to synthesize ZnO nano particles within the wool fabric. To do this, the pretreated wool fabric with protease was immersed in the solution of Zn(CH3COO)2, NH3 and Na(OH) as precursor and distilled water or water/ethanol mixture as the reaction environment. The samples were then subjected to daylight for 7 days. The reactive oxygen species produced as a result of photocatalytic activities of nano ZnO, which have potential of decomposing impurities of wool fibers including the natural pigments and waxes. This leads to the hydrophilic and roughly white wool fabric surface.
