Synthesis of ZnO Nanoparticles by Wire Explosion for Superhydrophobic Applications

Abstract:

Wire explosion technique was explored for producing ZnO nanoparticles. The ZnO nanoparticles were spherical with diameters less than 20 nm. The as-prepared nanoparticles are a mixture of Zn and ZnO based on the XRD analysis. However, the remaining Zn was oxidized upon sonication in the presence of oxygen gas. The ZnO nanoparticles were dispersed in ethanol and deposited on glass before dipping in a stearic acid solution. The coated glass exhibited a static water contact angle of nearly 150°, indicating excellent water repellency.
