Weathering protection of wood surfaces
Modern wooden constructions require - particularly for façades - visually attractive and durable surface coatings. However, various problems regarding the surface protection of weather exposed wood are still not satisfactorily solved and the durability is principally limited. In several research projects in cooperation with industrial partners new concepts and functionalized treatments (partly based on nanoscaled components) for an improved moisture, UV and biological protection are developed and their long-term durability is tested.
Currently three specific surface-related projects are running within the frame of NRP66 'Resource Wood': www.nfp66.ch
- Modified nanofibrillated cellulose in surface coatings (Link to project description http://www.nfp66.ch/E/projects/wood-material-for-components/cellulose-nanofibrils-wood-coatings/Pages/default.aspx )
- Wood surface functionalisation using photoinitiators (Link to project description http://www.nfp66.ch/E/projects/wood-material-for-components/wood-surface-functionalisation-photoinitiators/Pages/default.aspx )
- Development of a natural UV-protection of wood surfaces by cellulose-rich layers (Link to project description http://www.nfp66.ch/E/projects/wood-material-for-components/natural-uv-protection-wood-surfaces/Pages/default.aspx )
We also participate in the running COST-Action FP1006 'Bringing new functions to wood through surface modification'. (Link: http://cost-fp1006.fh-salzburg.ac.at/ )
