Synthesis WO3 nanoparticle via the electrochemical method and study its super-hydrophobicity properties

This work introduces a simple method to prepare WO3 nanoparticles via tungsten rod electrooxidation in the presence of NaCl solution as an electrolyte. In this process, WO3 nanoparticles with sizes between 10nm and 20 nm were prepared and characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), and energy dispersive X-ray spectroscopy (EDX) techniques. WO3 nanoparticles are used to modify polysiloxane surface. The WO3 coated polysiloxane surface showed a very high-water contact angle of 158°.
