“…A number of authors have previously described the operation of this atmospheric pressure plasma jet (APPJ) source [13][14][15][16][17]. A schematic diagram of the system is given in Figure 1, this illustrates how the blown arc is formed inside the arc cavity and ionized gas is expelled through the anode-nozzle [22 and 23].…”

“…Amongst the plasma activation studies reported to-date with this source are those that aim to enhance the surface energy of polyethylene prior to adhesive bonding [13], adhesion improvement [6] and textile polymer treatments [14]. This source has also been used in the deposition of plasma polymerized coatings for gas barrier applications [15] and corrosion protection [16,17]. These papers have mainly focused on the process outcome as a function of anode-nozzle speeds relative to the treated surface.…”

Plasma treatments are widely used to activate polymer surfaces prior to adhesive bonding. This study investigates the influence of plasma treatment conditions on the surface activation of a range of polymers using the PlasmaTreat (Open Air) system. In this study the effect of dc pulse plasma cycle time, compressed air flow rate and the plasma jet nozzle to substrate distance on the plasma discharge was examined. The influence that the dc pulse plasma cycle time parameter has on the activation of polypropylene, polystyrene and polycarbonate was also investigated. The level of polymer surface activation was evaluated based on the change in water contact angle after plasma treatment. The polymer surface properties were also monitored using AFM and XPS measurements. The heating effect of the plasma was monitored using both infrared thermographic camera and thermocouple measurements. Plasma diagnostics measurements were obtained using the photo‐diode and optical emission spectroscopy techniques. From this study it was concluded that for the PlasmaTreat system the level of plasma activation was closely correlated with the dc pulsed plasma cycle time, which is a measure of the plasma intensity. For example, the more intense plasma obtained with shorter cycle times gave higher levels of polymer activation. The optimized pulsed plasma cycle times were found to be specific for a given polymer type and related to their thermal properties. The pulsed cycle times were also found to correlate with both the substrate and plasma gas temperatures. magnified image

“…Specifically, two reactive systems will be examined: one will use oxygen and hexamethyldisiloxane (case a) and a second will use oxygen and carbon dioxide (case b) as adsorptive species. The required activation energy will be provided by a plasma source [16,17] and a laser source [18], respectively. Surface modification with thin films composed of organosilicon-based plasma polymers was reported to be a promising approach for the corrosion protection of magnesium alloys, e.g.…”

Accumulated ice on exposed surfaces leads to operational difficulties and extensive maintenance for power transmission lines, antennas, aircraft, ships, and ground transportation vehicles.In the present study, the low pressure plasma polymerized Hexamethyldisiloxane (PP-HMDSO) film is deposited on aluminum surfaces to create a superhydrophobic coating with icephobic properties. Prior to the deposition of this low surface energy coating, aluminum surfaces were anodized or immersed in boiling water to make micro/nano structured surfaces.Plasma parameters were optimized in order to find the best optimum conditions for having high static contact angle and low contact angle hysteresis. Hence, the Grey-based Taguchi method was used as one of the Design of Experiment (DOE) techniques. The stability of coatings was studied under accelerated aging conditions such as UV degradation, immersion in distilled water and different pH solutions, and several icing/deicing cycles. It was observed that the PP-HMDSO coatings are quite stable against UV exposure and immersion in distilled water. However, the icephobicity of the PP-HMDSO coating deposited on the anodized aluminum decreased after fifteen icing/de-icing cycles.The stability of the developed coating was improved against several icing/de-icing cycles by increasing the deposition time of plasma polymerized coating from 15 to 25 minutes. The results showed that increasing the deposition time of plasma polymerization leads to decrease of the ice adhesion strength of coatings on anodized aluminum while it has no significant effect on the PP-HMDSO coating deposited on a water-treated aluminum surface. Finally, the superhydrophobic PP-HMDSO coating also provides anti-corrosion protection for the aluminum substrate.
