Highlights
Preparation, characterization and properties of new, tannin-derived, porous materials:
- 7 successive generations of cellular materials :
1- rigid with formaldehyde and controlled structure
2- formaldehyde-free
3- modified with isocyanates (mixed physical/chemical foaming)
4- based on other kinds of tannins
5- flexible and semi-elastic
6- partly based on proteins
7- based on concentrated emulsions (polyHIPEs)
- aerogels, cryogels and xerogels, possibly comprising natural or synthetic polymers (lignins, proteins, phenolic oligomers, …)
- monodisperse particles or having unimodal mesoporosity
- derived carbonaceous or ceramic materials
Preparation, characterization and properties of carbonaceous adsorbents with controlled nanoporosity for:
hydrogen storage (6.6 wt. % at 77K)
water treatment (phenols, arsenic, dyes, …)
detection of traces of toxic or explosive molecules
