Solutions de cellulose et matériaux hybrides/composites à base de liquides ioniques et solvants alcalins

Abstract : Cellulose, as the most common organic compounds on Earth, and also the most abundant polysaccharide, is definitely an important natural resource. With the initiatives of replacing (partially) the conventional petrochemical polymers by bio-based polymers, cellulose has regained the researchers' interests in the last few decades, not only because it is renewable and biodegradable, but also due to interesting properties such as biocompatibility and chemical stability. Additionaly, cellulose properties can be further enhanced by chemical/physical modification or making composites with functional fillers.This study was to investigate several fundamental scientific aspects as cellulose dissolution, making cellulose-based materials from solutions, and test of new concepts as surface modification or coating at laboratory scale. We studied and will present in this manuscript the characterization and properties of both cellulose solutions in different solvents (aqueous sodium hydroxide and ionic liquid) and two types of cellulose-based hybrid materials (one with starch and the other with carbon black), which were all prepared from dissolved cellulose.
