| Abstract |
Environmentally friendly products are of great interest of society and thus for production processes. A current market analysis by European Bioplastics predicts a global grow of bioplastics production by more than 35 % between 2020 and 2025. [1] Surface properties play an important role in order to be able to process and recycle sustainable plastics industrially. This work focusses on sustainable ultra-thin coatings by the use of naturally occurring precursors (film-forming agents) in order to avoid petrochemical agents and to enable an improved circular economy. Using atmospheric pressure plasma technology bio-inspired precursors like bioavailable fatty acids (e.g. olive-, chia-, walnut oil) are deposited on the surface. These films will modify the properties of paper and packaging materials with regard to its water uptake, printability and if desired dirt-repellent or antimicrobial behavior will be obtained. This leads to an increasing resistance of these materials and thus make it usable for novel applications. Aim of this work is to establish a coating process for functional coating of bio-based and solvent-free starting materials to design sustainable surfaces that can be adapted to the desired material properties via selected process conditions. Therefore, variations of the process gas (type and gas flow) and precursor dosing, applied energy and deposition time will be examined and correlated with the surface properties achieved. This will lead to a predictive knowledge for a data-based process development in the future and to a scalability to an industrial applicable process. Because atmospheric pressure plasma coating technology can be easily integrated into process chains (e.g. roll-2-roll or sheet-2-sheet), further process steps can be carried out in-line.
