A short plasma pre-treatment can improve the barrier effect of a-C:H /a-Si:H multilayers on polymer substrates, while a prolonged treatment can negatively influence the properties. In this work, we are investigating the influence of different plasma particle species, namely ions, metastables and (V)UV-photons, during the surface activation in an inductively coupled plasma.
To separate the different species, we build an ion-repelling grid system (IReGS), which repels ions from the substrate. In a second approach we further separate the effect of argon metastables from the effect of (V)UV-photons.
The change in surface energy of the polymer substrate is than analyzed by contact angle measurements at different activation times and particle composition to find an optimal activation process.
