“…PA66 foils were also treated by the atmospheric pressure DBD air plasma by Kuzminova et al [ 24 ] using a semi-continuous mode. The power supply operated at the frequency of 22.5 kHz and discharge power of 30 W. The configuration was very similar to that adopted by Karoly et al [ 13 ].…”

A review of the most significant scientific achievements in the field of surface modification of polyamides by non-equilibrium plasma treatments is presented. Most authors employed atmospheric pressure discharges and reported improved wettability. The super-hydrophilic surface finish was only achieved using a low-pressure plasma reactor and prolonged treatment time, enabling both the nanostructuring and functionalization with polar functional groups. The average increase of the oxygen concentration as probed by XPS was about 10 at%, while the changes in nitrogen concentrations were marginal in almost all cases. The final static water contact angle decreased with the increasing treatment time, and the oxygen concentration decreased with the increasing discharge power. The need for plasma characterization for the interpretation of experimental results is stressed.

“…To improve the compatibility of the interlayer with TS, the surface has been modi ed by plasma treatment. Such fast treatment Kuzminova et al (2014) modi es the extreme surface by cleaning and chemical activating it, through the addition of radicals and polarity. Consequently, the done treatment will increase the compatibility with the resin, improve the inertness of the interlayer surface and will create strong chemical bond with the surface of the resin.…”

“…Through the proposed surface treatment by N 2 /O 2 (80/20) atmospheric plasma Kuzminova et al (2014) , the wettability of the three interlayer lms is improved through a cleaning and chemical activation. In order to better understand the time contribution of the treated surface, three post-treatment time are selected for this study: 1 minute, 3 days and 7 days after treatment.…”

Fusion assembly is a highly promising technique to join thermoplas- tic to thermoset composites, enabling the use of both the most affordable com- posite material and process for each sub structure.Yet, some major challenges need to be pull through such as the functionalizing of the thermoset compos- ite surface by co-curing an appropriate thermoplastic interlayer or realizing a fast and robust welding process that fulfils all quality and mechanical require- ments. In the present paper, we investigated the potential of Polyetherether- ketone (PEEK) and its amorphous (PEEK A) and semi-cristalline (PEEK SC) states as interlayer materials, co-cured onto the thermoset composite. A surface preparation by atmospheric plasma process demonstrated that both PEEK state materials can be used as interlayer with auspicious resulting ad- hesion properties. The influence of the plasma treatment on surface properties and morphology is also experimentally characterized. An infrared (IR) welding process, barely studied in the literature, is studied to assemble hybrid struc- tural composite. In order to avoid the expected thermal degradation of the thermoset matrix, a dissimilar infrared heating input power is proposed. More- over, to decrease the possible thermal degradation of the thermoset composites during the fusion bonding, a dissimilar infrared welding process have been ex- plored. Single lap shear test and failure mode analysis have been performed to highlight the promising performance of PEI as well as PEEK interlayer based hybrid joint.

“…Different methods can be used for modification of the polymer surface properties, including chemical treatments, irradiation with photons, irradiation with ion or electron beams and treatment by gaseous plasmas created by electric discharges (corona, dielectric barrier discharge, glow discharge, etc.). Among all of these methods, plasma treatments remain the most prominent techniques for surface modification [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ]. By appropriate selection of the type of discharge, treatment conditions, and working gases, it is possible to graft different surface functional groups, to change surface morphology, and even to create nanostructures on the treated surface.…”

Cell Proliferation on Polyethylene Terephthalate Treated in Plasma Created in SO2/O2 Mixtures

Samples of polymer polyethylene terephthalate were exposed to a weakly ionized gaseous plasma to modify the polymer surface properties for better cell cultivation. The gases used for treatment were sulfur dioxide and oxygen of various partial pressures. Plasma was created by an electrodeless radio frequency discharge at a total pressure of 60 Pa. X-ray photoelectron spectroscopy showed weak functionalization of the samples' surfaces with the sulfur, with a concentration around 2.5 at %, whereas the oxygen concentration remained at the level of untreated samples, except when the gas mixture with oxygen concentration above 90% was used. Atomic force microscopy revealed highly altered morphology of plasma-treated samples; however, at high oxygen partial pressures this morphology vanished. The samples were then incubated with human umbilical vein endothelial cells. Biological tests to determine endothelialization and possible toxicity of the plasma-treated polyethylene terephthalate samples were performed. Cell metabolic activity (MTT) and in vitro toxic effects of unknown compounds (TOX) were assayed to determine the biocompatibility of the treated substrates. The biocompatibility demonstrated a well-pronounced maximum versus gas composition which correlated well with development of the surface morphology.
