Great future for biobased aerogels
New exciting results on biobased aerogels (bio-aerogels) were obtained in the group of Tatiana Budtova. Fifteen years of research in this area resulted in breakthrough advancements.
Lucile Druel started her PhD thesis in the frame of this project, supervised by Tatiana. The scientific literature on this topic was practically non-existent. They tried to reproduce the published results but without success. However, they managed to develop a new approach and obtained aerogel beads of 20 microns in diameter.
Tatiana explains: « Now our method is reliable and reproducible. It is a result of a fruitful collaboration with colleagues from Hamburg University of Technology. This is a great advantage of common research projects.”
Our story could stop here …. But research continues. In fact, to make aerogels a special drying, in supercritical conditions, is needed. This is to remove the solvent from the gel and preserve its porosity and nanostructure, which results in exceptional properties of aerogels: very low density, high adsorption capacity and insulation properties.
« We were working following our intuition, but it is based on a long-lasting expertise in cellulose aerogels” said Tatiana.
Lucile Druel will defend her PhD thesis "Cellulose based aerogels: properties and shaping as beads" on May 10th, 2019.
