FAçade bio-CArbon based anti UV coating to prevent DEterioration of wooden buildings
Façades play crucial roles in the building safety, comfort, and aesthetics. As an envelope for buildings, they are in constant interaction with outside environment. In Europe, the construction sector is one of the highest energy consumers and one of the main contributors of greenhouse gas emissions. The building industry is one of the key enablers for the 2050 decarbonisation goal in the EU economy. Therefore, enhancing the sustainability of construction materials is a key priority. Wooden facades are attractive due to their pleasant aesthetics and to the use of renewable resources for building. However, wooden materials are sensitive to the exposure in the outside environment. Indeed, ultraviolet (UV) solar radiation absorbed by lignin – constituting up to 40% of wood – initiates the weathering of wood. It is therefore crucial to limit the weathering effects that can then lead to deterioration of wood by using coatings to protect its surface. The FAÇADE project proposes to develop a competitive and sustainable bio-sourced anti-UV coating to protect wooden façades, using bio-carbon as UV-absorber. The specific objectives of the project are: – To perform an in-depth analysis of the effect of biomass carbonization processes on the structure and properties of bio-carbon needed for UV protection. – To develop an efficient and reliable process to convert microscale bio-carbon particles to nanosized carbon particles without damaging the inherent structure. – To manufacture a novel, fully bio-based anti-UV coating and to assess the anti-UV performance on different wood species.

Project objective
Façades play crucial roles in the building safety, comfort, and aesthetics. As an envelope for buildings, they are in constant interaction with outside environment. Ultraviolet (UV) solar radiation absorbed by lignin – constituting up to 40% of wood – initiates the weathering of wood. The weathering process induces colour changes, surface fibres to loosen and erode, allowing humidity to penetrate in depth in wood, and causing checks and a raised grain. It is therefore crucial to limit the weathering effects that can then lead to deterioration of wood by using coatings to protect its surface. UV absorbers enhance the durability of wood outdoors by absorbing incident radiation and by converting it into heat, which is then dissipated. Carbon-based materials are potential UV stabilizers thanks to combined effects of physical screen, UV absorbance, and radical trap. Bio-carbon is a carbon-based product obtained from thermal decomposition of organic materials at elevated temperatures. Organic materials can be wastes from the agricultural or forest industries, with currently little or no economic value. Bio-carbon presents a wide range of properties that can be tailored by the manufacturing process. To the best knowledge of the Experienced Researcher (ER), no prior research on using bio-carbon for UV stabilization has been reported. The FACADE project proposes to develop a competitive sustainable bio-sourced anti-UV coating to protect wooden façades, using bio-carbon as UV-stabilizer. The FACADE project tackles challenging concepts with innovative solutions and is expected to provide breakthroughs for advancing the use of bio-carbon in new applications and proving a fundamental understanding of the UV protection mechanisms of nanoscale carbon particles. Through the MSCA program activities, particularly mentoring young researchers, organizing events and managing projects, the ER will make a significant step in her career by gaining professional maturity and independence.
