Atmospheric pressure plasma jet for surface material modification: a mini-review

Abstract

Abstract Plasma jet is one of the methods for surface material modification that is economically and environmentally friendly. This method can be applied in ambient pressure that makes this method more feasible. The discharge of plasma from the plasma jet can be adjusted according to the design used. Carrier gas that is used in the plasma jet system can also be adapted to the needs or appropriate to the target material. The gases that can be used are helium, argon, etc. A variant gas flow rate will also affect the plasma species and the surface material characteristics produced. Modifying a material with certain compounds can be done by passing the active gases or vapors through the carrier gas. The use of the plasma jet method possibly converts the surface material to be hydrophobic or hydrophilic characteristics. Moreover, the plasma jet technique is applicable for various materials or substrates in any dimension. This review article will discuss the parameters applied, such as various designs, carrier gas, gas flow rates, power used in the plasma jet.
