- Polyhydroxyalkanoates (PHAs)
- Chemical modification
- Biobased molecules and polymers
Among biodegradable polymers, aliphatic polyesters obtained mainly by bacterial fermentation, such as polyhydroxyalkanoates (PHAs), are candidates offering an alternative in several cases to petroleum-derived polymers due to the diversity of structures. Matching the material properties to the application involves chemical modification of PHAs and/or their association with other polymers by copolymerization or blending. The researches carried out on a panel of chemical modifications enable the development of new tools for the biomedical (proadhesive surfaces, tissue engineering, stimulable materials…) or environmental (antifouling coating) fields.
The development of new fully biobased composite materials is part of a context of developing agro-resources. One line of research aims to develop new polymer materials from biobased synthons as phenolic and terpene derivatives. Thiolene or photo-initiated cationic polymerization reactions are used to develop antibacterial and antioxidant materials. These platform molecules are also chemically modified to prepare structural materials for sustainable construction.
