Cellulose

Cellulose

Elise Billès Thesis (2012-2015), the objective is to obtain hybrid materials from cellulose. For this purpose, the cellulose is enzymatically depolymerized to recover size-controlled oligomers. They are then functionalized and copolymerized with other natural or synthetic oligomers. The materials thus formed will have the properties of two blocs used as well as new properties arasing form their association. 

Jérémie Brand thesis (2013-2016), ISOCEL project (Innovative SOlar CELls))
In order to protect the rear side of the solar panels from oxygen and humidity, a polymeric protective layer is necessary. The innovative character of this project comes from the use of nano crystal cellulose(NCC), in order to improve the barrier properties (to water and oxygen). These biosourced crystals are  then chemically modified depending on the polymer matrice used. The final aim is to obtain a cheaper material to produce, easier to implement and more environmentally friendly.
