Design and synthesis of biobased epoxy thermosets from biorenewable resources

Abstract: International audienceBiobased 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 thermal and mechanical properties comparable to those obtained with conventional petrosourced DGEBA-based epoxy resins cured in similar condit… Show more

“…This way induces a variability of the resulting materials properties since the content of lignin in different types of biomass resources varies strongly. An alternative approach consists of lignin fragmentation [10][11][12] leading to a wide range of building blocks, such as vanillin [13][14][15], rosin [16], eugenol [17][18][19][20] and isoeugenol [21,22], which are then epoxidized.Within this context, our research team has recently described both the synthesis of an epoxy monomer derived from isoeugenol, named as GlycidylEther Epoxy isoeugenol (GEEpiE) [21], and its curing with camphoric anhydride [22]. Behaviours of the resulting thermoset are consistent with its use as a bio-based epoxy matrix for structural composites.…”

“…Another vanillin‐based cured epoxy resins of 2,5‐bis(4‐hydroxy‐3‐methoxybenzylidene) cyclopenta‐none‐digycidyl ether showed T g values in 121–130°C range . In addition, the commercial bio‐sourced epoxy materials are known to have low T g values; for example: Epobiox Sandtech T g = 80°C and Greenpoxy Sicomin T g = 85°C . Thus, our biobased epoxy resins, in particularly 1,6‐diamino hexane and IPDA‐cured resins 6 and 7 , displayed much higher T g values.…”

“…Thus, our biobased epoxy resins, in particularly 1,6‐diamino hexane and IPDA‐cured resins 6 and 7 , displayed much higher T g values. Furthermore, glass transition temperatures of these hydrovanilloin epoxy resins are comparable to commercially available diglycidyl ether of bisphenol A (DGEBA)—polyamine epoxy resins—which are typically in the range of 120–150°C . The total heat absorbed in the glass transition (Δ H ) for 3‐7 are also listed in Table .…”
