“…However, when using the wire mounting, for higher d values (12.0 and 15.0 mm), the WCA reduction at the sample center was higher than those measured in the neighborhood. Similar behavior in the WCA distribution was already observed on plasma-treated polyethylene terephthalate (PET) by Narimisa et al [ 32 ]. In that work, the authors used a pin-ring electrode configuration to produce a plasma jet using Ar as the working gas.…”

“…Most of the works on polymer surface treatment by APPJs report similar modification profiles, obtained through WCA measurements, that resemble an inverted Gaussian profile [ 5 , 30 , 31 ]. A work by Naramisa et al presents a slightly different WCA profile, with a deeper WCA reduction close to the spot where the plasma impinges the target [ 32 ]. A work by Shao et al reported that the WCA reduction as a function of the distance d between the plasma outlet and the target surface does not present a monotonic behavior as a function of d when polymethyl–methacrylate samples are exposed to plasma treatment [ 33 ].…”

The plasma jet transfer technique relies on a conductive wire at floating potential, which, upon entering in contact with a primary discharge, is capable of igniting a small plasma plume at the distal end of a long flexible plastic tube. In this work, two different long tube configurations were employed for the surface modification of polypropylene (PP) samples using argon as the working gas. One of the jet configurations has a thin copper (Cu) wire, which was installed inside the long tube. In the other configuration, the floating electrode is a metallic mesh placed between two plastic tubes in a coaxial arrangement. In the first case, the tip of the Cu wire is in direct contact with the working gas at the plasma outlet, whereas, in the second, the inner plastic tube provides an additional dielectric barrier that prevents the conductor from being in contact with the gas. Water contact angle (WCA) measurements on treated PP samples revealed that different surface modification radial profiles are formed when the distance (d) between the plasma outlet and target is changed. Moreover, it was found that the highest WCA reduction does not always occur at the point where the plasma impinges the surface of the material, especially when the d value is small. Through X-ray photoelectron spectroscopy (XPS) analysis, it was confirmed that the WCA values are directly linked to the oxygen-functional groups formed on the PP surfaces after the plasma treatment. An analysis of the WCA measurements along the surface, as well as their temporal evolution, together with the XPS data, suggest that, when the treatment is performed at small d values, the plasma jet removes some functional groups at the point where the plasma hits the surface, thus leading to peculiar WCA profiles.

“…In this study, a modified homemade APPJ, previously described and applied for the treatment of polymer surfaces was used. [ 33 ] To introduce a stream of shield gas into the plasma effluent, small adaptations to the plasma jet were done, which will be described hereafter. First, three holes have been drilled in a polyvinyl chloride (PVC) disk (5 mm thickness and 60 mm diameter) at a 45° angle towards the plasma effluent and at a 10 mm radial distance from the capillary center in such a way that every single hole is equidistant from the two other holes.…”

“…The system uses argon gas with a gas flow rate of 1 L/min as working gas and a mixture of argon gas and nitrogen gas as shielding gas with a gas flow rate of 1 L/min. This system used an HV AC power supply with a 60 kHz frequency and a fixed amplitude of 8 kV [17]. Pav represents the total power absorbed, and 2AnevbElost represents the total power of discharge over the area 2A of the electrodes, ne is the electron density, Elost is the energy lost per cycle, and vb is the Bohm velocity.…”

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.
