CALL FOR EUROPEAN PARTNERS Research and Innovation on the Wood - Coating Interface and Modified Wood for Prolonged Service Life of Wooden Components in Outdoor Constructions • Developing a wood protection coating that adheres chemically to wood by adapting techniques from wood modification and functionalization of other polymers to coating systems • Service Life Prediction supported by in situ moisture measurements and modeling in wood claddings and panels • Durability mechanisms in modified wood • Redefining performance testing of material properties in modified wood using spectroscopy and multivariate modeling • Contact details
Chemical Adhesion of Wood Coatings Technologies from wood modification studies and functionalization of other polymers can be extended to wood coating technology to improve bonding strength in the wood - coating interface Novel techniques in surface analysis on molecular level and accelerated testing methods will be implemented in evaluation of new properties UNTREATED – POOR ADHESION MODIFIED WOOD – GOOD ADHESION Modified from: Holz als Roh - und Werkstoff 59 (2001) 319-326
In situ Moisture Measurements and Service Life Prediction through Modeling Realistic modeling of resistance in situ measurements to a prediction factor for Service Life of wood claddings and panel elements Comparison of data from other European countries in similar set-ups Figure: Data analysis performed by Emil Engelund, Technical University of Denmark, 2007
Durability Mechanisms in Modified Wood A holistic approach to wood modification: How does it work? • Physical protection – bulking mode-of-action investigated directly by Scanning Electron Microscopy and indirectly by sorption modeling • Chemical blocking – revealed by qualitative Infrared Spectroscopy analyses • Enzymatic blocking – hydrolysis of wood constituents to map possible mechanisms
Chemometrics on Performance Testing Multivariate non-destructive methods to explore material properties in wood using FT-NIR/ATR-IR spectroscopy data and regression modeling Chemical information from spectral data Modeling Prediction of properties Figure: Data analysis performed by Thomas Mark Venås, Danish Technical Institute Denmark, 2007
