High performance materials based on regrowing resources

The challenge of the climate crisis requires novel bio-based and CO2 binding, as well as functionalized high-performance materials that go beyond the state of the art. Wood as a renewable raw material offers the basis for such materials, but due to its naturalness also material-technical challenges prevail that need to be overcome. In the course of a strategic project, three main topics were specifically addressed with new methods that play a key role in the development of bio-based materials. As a result, fundamental steps in the UV and water protection of wood surfaces were achieved, which will significantly influence the further development of natural wood surface treatments. By specifically reducing the density of bark through delignification processes or by combining it with newly formulated bio-based matrix materials, it was possible to create highly porous material structures with outstanding insulating properties. In the area of sustainable and bio-based bonding of wood-based materials, the targeted modification and cross-linking of plant proteins enabled the formulation of binders that are not only bio-based but also have increased wet strength. The project has enabled fundamental steps to be taken towards sustainable and biobased wood-based materials, which will form the basis for future material developments to substitute fossil-based materials.
