Abstract

Plasma surface treatments are common in many sectors like the polymer industry. For biobased materials, surface modifications are often required for further processing, but plasma is barely used due to diverse chemical composition and heterogeneous structure significantly influencing the physics and chemistry within the plasma. Moreover, typical atmospheric pressure plasmas are limited in their ability to treat bio-based materials regarding specimen dimensions, tolerances and stability.

Diffuse coplanar surface barrier discharge (DCSBD) plasmas are highly effective for large area flat surface treatment, but the active plasma thickness is limited and cannot be applied to structured surfaces. Floating-electrode dielectric barrier discharges (FEDBD) plasmas utilize the work pieces’ surface as intermediate electrodes, but to date cannot treat all bio-based materials without dimensional limitations.

This project combines DCSBD and FEDBD plasmas into a hybrid surface-to-volume discharge to overcome previous limitations and research its interactions with bio-based materials.
