Description
Due to its piezoelectric properties, zinc oxide (ZnO) is a promising candidate as a sensor material for condition monitoring and in haptic sensors, especially in the form of nanowires (NWs).
Although there are many ways to synthesize ZnO-NWs, such as the hydrothermal growth, the plasma flight-thru process offers several advantages, namely short process times, high throughput and cost-efficiency.
In the present work, we study the influence of energy and oxygen content on the shape of ZnO-NWs, which were synthesized with an atmospheric pressure hot plasma jet based on a direct current arc discharge.
Depending on the reaction conditions, SEM images taken from the samples show a great variety of structures, including half-molten particles, nanowires and filigree nanoscale networks.
After further optimization, we will be able to synthesize and harvest ZnO-NWs in a semi-continuous, cost-efficient way, so that we will meet the requirements needed in condition monitoring and haptic sensors, soon.
