Abstract

In this study, electro-spray device with super-hydrophobic nozzle is presented and fabricated instead of protruded nozzle. The super-hydrophobic nozzle is created by roughening the surface of the polyfluorotetraethylene (PTFE) or Teflon coated surface by argon and oxygen plasma treatment. We present a simple process of fabricating super-hydrophobic nozzle which is able to allow itself to enhance the stability of liquid meniscus at the outlet of the nozzle. Through the ion beam treated nozzle, the liquid does not overflow and keeps more stable and repeatable ejection of liquid jet.
