This research project aims to explore bio-based and biodegradable alternatives prepared according to more sustainable manufacturing processes in order to mitigate the environmental impact. To achieve this, a family of 100% bio-based superabsorbents polymers will be synthesized from abundant renewable compounds, such as itaconic acid, homocysteine thiolactone, chitosan polysaccharide or citric acid. Three different synthesis strategies based on a 100% atom efficient “click chemistry” concept will be developed resulting in different architectures and properties.

A particular attention will be paid to ensure that the syntheses are carried out under sustainable conditions (green solvent, room temperature and atmospheric pressure). Physico-chemical properties of the SAP hydrogels will be determined, in particular the biodegradability, the liquid absorption capacity and the mechanical strength of the hydrated product. The materials synthesized are designed to meet a strong social and regulatory demand. The synthesized materials would meet a strong societal and regulatory demand, and therefore have a high potential for industrial development.
