Congratulations to Maylis Carrère for first prize in the «CRIBIQ Student Symposium 2023 poster competition»!
Congratulations to Maylis Carrère for winning first prize in the poster competition at the Student Symposium 2023 of the Consortium for Research and Innovation in Industrial Bioprocesses in Quebec (CRIBIQ)!
Maylis Carrère, a doctoral candidate in wood and bio-based materials engineering at Laval University under the supervision of Professor Véronic Landry, had the opportunity on November 30, 2023, to participate in the 6th edition of the CRIBIQ student symposium in Victoriaville, with the theme «The Quebec bioeconomy: challenges, issues and solutions for a sustainable future». As part of the event, she was able to present the results of her research on the «Development of biobased coatings for exterior wood products» in poster form and interact with the participants, earning her first prize in the poster competition.
Well done Maylis, this prize rewards your efforts and determination!
SUMMARY
Wood is a natural material with many interesting physical and mechanical properties, such as resistance to thermal change and insulating capacity, making it suitable for use as a building material. In the building sector, it is used in particular as exterior cladding. However, wood can be weakened by climatic conditions (wind, rain, sun, temperature variations) and by micro-organisms. To preserve their properties and aesthetics, exterior wood surfaces are generally protected by a coating. Water-based coatings are most often prepared using emulsion polymerization technology. Until now, most latexes have been prepared from petrochemicals (acrylate monomers, for example). To reduce the environmental impact of these coatings, the use of biobased raw materials is being considered. The main objective of this project is to develop a coating for exterior wood based on local biosourced raw materials. Wood extractives will be functionalized with (meth)acrylate groups and then polymerized by miniemulsion to create biobased latexes. Glass transition temperature and latex particle size were determined by differential scanning calorimetry (DSC) and dynamic light scattering. The integration of (meth)acrylated biobased monomers has been confirmed by chromatography (Py-GC-MS).
