Epoxy resin plays a key role in composite matrices and DGEBA is the major precursor used. With the aim of favouring the use of bio resources, epoxy resins can be prepared from lignin. In particular, diglycidyl ether of isoeugenol derivatives are good candidates for the replacement of DGEBA. This article presents an effective and eco-friendly way to...
Article
A bio-based reactive phosphate flame retardant derived from iso-eugenol was synthesized and fully characterized (1H,13C,31P NMR, FTIR, MS) with the aim of improving flame retardancy behavior of bio-based epoxy thermosets. This new green flame retardant, diepoxy-iso-eugenol phenylphosphate (DEpiEPP) was then copolymerized either with conventional di...
Article
Biobased diepoxy synthons derived from isoeugenol, eugenol or resorcinol (DGE-isoEu, DGE-Eu and DGER, respectively) have been used as epoxy monomers in replacement of the diglycidyl ether of bisphenol A (DGEBA). Their curing with six different biobased anhydride hardeners leads to fully biobased epoxy thermosets. These materials exhibit interesting...
Article
In this works, we have explored a new method for a green synthesis of poly(ethylglyoxylate) (PEtG).

Article
BABA is a non-protein amino acid inducing resistance in many different plant species against a wide range of (a)biotic stresses. Nevertheless, how BABA primes plant natural defence reactions remains poorly understood. Based on its structure, we hypothesized and confirmed that BABA is able to chelate iron (Fe) in vitro. In vivo, we showed that it le...
