“…The method of determining the adhesive energy is inspired by the work of Rombaldoni et al [9] The resulting data for treated and untreated PP substrate are shown in Table 2. These results are of good order in correlation with our previous publication [5], where a different type of test was performed to determine the adhesive energy. Specifically, in this work the tearing test was proved of 180° sample attachment in mechanical jaws.…”

The aim of this work was to determine the effect of plasma on the substrate and on the nanofibers themselves. The PA6 nanofibrous material and the PP carrier were exposed to the effects of dielectric barrier plasma generated in air at atmospheric pressure. Changes in chemical composition, the effect on adhesions to the support substrate and especially the plasma effect on the filtration efficiency of the nanofiber material were studied.

“…In this way, we obtain a functional, inexpensive nanomaterial that we can use for products with high added value. [5,6] In this work, we focused on the use of dielectric barrier discharges in a coplanar arrangement. These plasma sources are able to generate low temperature energetic plasma over a relatively large area.…”

“…Currently, DBDs with advanced configurations involving for instance convexly curved electrodes are being designed for the plasma treatment of sensitive materials such as polymeric nanofibers. In contrast to the traditional DBD reactors, the newly designed reactors were shown to allow an effective air plasma surface activation of electrospun nanofibers without any significant etching and degradation 47 .…”

“…Shepa et al studied the impact of plasma treatment on the different atmospheres on the surface of the polymer TiO2/PVP microfibers, prepared by needleless electrospinning technology [19]. Pavli ňák et al studied nanofiber carriers, polypropylene nonwoven textile and paper, which were pretreated by dielectric barrier discharge in continuous mode to improve the adhesion between the produced nanofibers and substrate [20]. Trejbal et al demonstrated the influence of plasma treatment on the surface properties of PET fibers used as micro reinforcement in cementitious composites [21].…”

DMA Analysis of Plasma Modified PVC Films and the Nature of Initiated Surface Changes

The application of DCSBD (Diffuse Coplanar Surface Barrier Discharge) plasma is referred to as the surface modification/activation of materials. The exposure of material surfaces to DCSBD plasma is initiated by changes in their chemical composition, surface wettability and roughness. The given study presents the mentioned plasma application in the context of the modification of the material viscoelastic properties, namely the PVC polymer film. The measurement of viscoelastic properties changes of PVC was primarily examined by a sensitive thermal method of dynamic-mechanical analysis. This analysis allows identifying changes in the glass transition temperature of PVC, before and after DCSBD plasma application, Tangens Delta, supported by glass transition temperatures of Elastic and Loss modulus. The results of the present study prove that DCSBD plasma applied on both sides to PVC surfaces causes changes in its viscoelastic properties. In addition, these changes are presented depending on the variability of the material position, with respect to the winding of the electrodes in the ceramic dielectric generating the DCSBD plasma during modification. The variability of the PVC position holds an important role, as it determines the proportion of filamentous and diffuse components of the plasma that will interact with the material surface during modification. The application of DCSBD plasma must, therefore, be considered a complex modification of the material, and as a result, non-surface changes must also be considered.
