After the optimal velocity profile was obtained, the end goal of mixing two process gases in order to obtain a diffusion gradi ent could be started. For this purpose, two flow spreading inlets were used with a single outlet. Two different feed gases were then utilized and a diffusion model based on gas kinetic theory was applied. 7). 7 The numbers correspond to H 2 concentration distribution (mol %) obtained within the porous metal plate as calculated by Fluent™. N 2 and N 2 + H 2 gas flows enter the porous plate homogeneously distributed over the upper and the lower halves of the left edge of the plate, resp.
4 SEM micrographs of copper-plated a) untreated and b) plasma-treated (before plating for 2 s each side) 50 g/m 2 polypropylene nonwoven fabric . 40 ATMOSPHERIC PRESSURE PLASMA TREATMENT OF POLYMERS Adhesion of both Ni and Co layers to untreated substrates was low, and almost all metal layers were easily peeled off the fabric. The adhesion of metal layers to plasma-treated fabrics was much higher: indeed, it was not possible to remove the metal layers without separating the fibres of fabrics.
3 Results and Discussion Gradient polymer surfaces were successfully fabricated at atmo spheric pressure using porous plasma stamps and a short contact with microcavity discharges in N-containing gases with a concen tration gradient of H 2 in the plasma. Due to the fact that plasmamodified thin film compositions were generated over a relatively small area, 36 x 36 mm 2 , the samples were well-suited to carry out surface analyses with quantitative FTIR-ATR and SEM-EDX methods. Combinatorial studies on plasma-printed gradient arrays were conducted in order to discover the influence of hydrogen con centration c in nitrogen (0 < c < 4 %) on functional groups densi ties and their subsequent metallization behaviour.
