Synthesis of biosourced amphiphilic bioconjugates from xylans and fatty acid derivatives
The development of bio-based polymers is a priority area listed in the roadmap established at national and European level. However, many scientific and technological obstacles remain to be overcome.
The first is certainly the extraction, purification and characterisation of the natural biopolymers that generally constitute the plant wall (cellulose, hemicelluloses, lignin) or that are stored in reserve tissues (starch, lipids). Secondly, it is usually necessary to modify their chemical structures or to combine them with other polymers to extend their fields of application. In order to meet these challenges, we propose to design new copolymers integrating natural polysaccharides and lipid sequences by coupling reaction.
To address these challenges, we propose to design new copolymers integrating natural polysaccharides and lipid sequences by coupling reaction.
Project objectives
- To develop original and innovative methodologies for the extraction, preparation and purification of hemicelluloses/oligosacharides and fats for the production of amphiphilic copolymers,
- Designing new copolymers incorporating wood xylans and modified fatty acid derivatives,
- To optimise the synthesis and up-scaling conditions of the copolymers produced at laboratory scale so far,
- To study the physico-chemical behaviour of the copolymers obtained.
