When the meniscus of liquid is subject to strong electric field, electric charge is induced on the meniscus and electrostatic force elongates the liquid to form a cone-jet. This electrospray phenomenon can be applied to many fields. Because the hydrophobicity may enhance the stability of liquid meniscus and jet formation, this article presents polymer based electrospray device with super-hydrophobic nozzle surface treated by oxygen plasma process.
