Descripción del proyecto
Los edificios se recubren de una nueva película de protección contra la radiación solar ultravioleta
El desgaste provocado por la intemperie afecta considerablemente al aspecto de los edificios. Por ejemplo, los revestimientos son vulnerables a los efectos adversos de la radiación solar ultravioleta (UV). Además, cuando la lignina (que constituye hasta el 40 % de la madera) absorbe los rayos del sol, se pone en marcha el desgaste de la madera, que produce cambios de color. Esta radiación también provoca que las fibras superficiales se distiendan y erosionen, permitiendo la penetración de humedad hasta capas profundas de la madera, así como la formación de grietas y el relieve de las vetas. El proyecto financiado con fondos europeos FACADE utilizará biomateriales para desarrollar una película para la construcción. En particular, utilizará el biocarbono como estabilizador de los rayos UV para obtener un material de recubrimiento contra estos rayos a partir de fuentes biológicas sostenibles para proteger las fachadas de madera. En última instancia, el proyecto dará un gran impulso a la utilización del biocarbono en nuevas aplicaciones.
Objetivo
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.
