Abstract :
this work introduces a simple method to prepare wo_3 nanoparticles via tungsten rod electrooxidation in the presence of nacl solution as an electrolyte. in this process, wo_3 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. wo_3 nanoparticles are used to modify polysiloxane surface. the wo_3 coated polysiloxane surface showed a very high-water contact angle of 158°.
