“…According to Ref. [14], the increase range of Ceff value directly revealed the degradation degree Figure 4 shows the time dependence of the consumed power for three plasma devices. It can be seen that the consumed power values of the two fluorinated devices were higher than that of the un-fluorinated one at the aging time of 0 h, then, the consumed power of the three devices increased with the aging time; this was mainly because the plasma was situated nearer the grounded electrode with the degradation of the top PI layer, and therefore in a region where the expected electric field strength was higher [14].…”

“…Pons et al [12] showed that degradation of two sorts of polymers (Poly methyl methacrylate and Polyvinyl chloride) occurred when they were exposed to 10 min of plasma operation in ambient air. Hanson et al [14] and Ndong et al [15] experimentally showed that degradation of PI-based actuators was accompanied by an increase of power consumption after plasma processing. Rigit et al [16] found that plasma actuators manufactured from PCBs were visually shown to degrade and fail in some instances.…”

Abstract:In this work, multi-layered polyimide (PI) films were surface fluorinated at 328 K and 0.05 MPa using F 2 /N 2 mixture with 20% F 2 by volume, for a fluorination time of 0, 30 and 60 min, respectively. Then, they were subjected to discharge plasma as barrier dielectrics of surface dielectric barrier discharge (SDBD) at ambient atmospheric air. The dielectric lifetime of SDBD greatly extends after 60 min surface fluorination. In addition, optical emission spectroscopy (OES) results indicate that during the plasma processing, SDBD with fluorinated PI can obtain more stable plasma parameters, including gas temperature and electron temperature. Dielectric surface properties were further evaluated by infrared thermography, scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS). It is considered that both physical and chemical effects lead to the extension of dielectric lifetime. The physical effect is reflected in low surface temperature and increased surface roughness, while the chemical effect is reflected in the graft of fluorine groups.

Dielectric barrier discharge (DBD) plasma actuators are simple electrohydrodynamic devices, which are able to provide effective aerodynamic control. One of the main components of these devices is the thin dielectric layer, which allows to separate and prevent the arc between the high‐voltage electrodes. Different materials can be used as dielectric layer to reduce the power consumption or boost the flow controlling effect of the actuators. In this context, this report presents a comparative study of two commercial polyimides, Kapton and Cirlex, used as dielectric layer of surface DBD plasma actuators. The electrical, dielectric, mechanical, electromechanical, and thermal properties were obtained to evaluate overall performance. It was verified that Cirlex (8.3 W) consumes less power than Kapton (21.3 W) to generate higher induced flow velocity of ≈3.4 m/s for an input voltage of 11 kVpp and 24 kHz. During one AC cycle at 11 kVpp the charge transferred for Cirlex (70 nC) is lower than for Kapton (100 nC), as well as the dielectric breakdown voltage to ignite the plasma discharge, 1.5 and 2.2 kVpp, respectively. The Cirlex DBD presents a higher voltage operation limit (at least 14 kVpp) and a more regular plasma discharge, which results in a more homogenous thermal profile and temperature distribution during its operation. The Cirlex actuator delivered higher mechanical power (6.2 mW) and achieved higher electromechanical efficiency (0.004%). The polyimide Cirlex proved to be a suitable alternative for Kapton to fabricate DBD plasma actuators for flow control with improved performance.

Surface dielectric barrier discharge (SDBD) is widely applied in the field of active flow control. Its carrier is usually called plasma actuator (PA). However, it has a key drawback of short discharge lifetime due to the dielectric degradation under plasma processing. In this paper, polyimide (PI) film incorporated with Al2O3 nanoparticles is fabricated and used as dielectric of PA. Dielectric material, plasma, surface temperature, discharge characteristics as well as its performance are experimentally studied and compared with those of a conventional pure PI based control actuator. The results show that at sine peak to peak voltage of 8 kV and 6 kHz frequency, the force efficiency of new designed actuator is 2.5 times higher than that of the control actuator after 30 h discharge. Besides, the discharge lifetime is also 3.2 times as long. In the discharge region, the surface of the control actuator appears serious dielectric degradation, which is accompanied by heat accumulation as well as an increase of gas temperature and electron temperature. While for the new actuator, after selective plasma etching, the inorganic Al2O3 nanoparticles can continuously resist the discharge plasma and contributes to effective heat dissipation and more stable plasma parameters.
