Deposition of Nanostructure ZnO with Variable Morphology by Electrochemical and Hydrothermal Methods onto Nonwoven Materials

Abstract:

ZnO nanostructures were synthesized by two wet-chemical methods (hydrothermal and electrochemical) featuring low temperature (95°C) and atmospheric pressure onto nonwoven substrates. We investigated a hydrothermal method using reagents Zn (NO₃)₂.6H₂O and hexamethylenetetramine (HMTA) as well as an electrochemical method using ZnCl₂, and KCl containing electrolyte with H₂O₂ and/or O₂ bubbling. The surface condition of substrate material and the experimental conditions played a key role in the nanowire formation. The morphologies observed by scanning electron microscopy (SEM) include wurtzit or cabbage-like. These morphologies were found to vary with the method applied.
