Biobased resins and composites with high biobased carbon content were prepd. and characterized. Epoxidized linseed oil (ELO) was copolymd. with four cyclic anhydrides, the initiation step being optimized in terms of initiator nature and its ratio. The optimized ELO/anhydride formulations were combined with a high load of lignin, as biofiller,...

Biorefinery by-products have received much attention in the last few years. Humins are one of these candidates. Nevertheless, one common feature of humins, as a polyfuranic thermoset material, is their inherent brittleness which is a direct consequence of the network's structure. Auto-crosslinked humins networks exhibit only minor deformation...

Among the biopolymers from animal sources, keratin is one the most abundant, with a major contribution from side stream products from cattle, ovine and poultry industry, offering many opportunities to produce cost-effective and sustainable advanced materials. Although many reviews have discussed the application of keratin in polymer-based...

The design of polymers from renewable resources with recycling potential comes from economic and environmental problems. This work focused on the impact of disulfide bonds in the dicarboxylic acids reactions with three epoxidized vegetable oils (EVOs). For the first time, the comparison between arom. vs. aliph. dicarboxylic acids, contg. or...

The combination of eco-respectful epoxy compounds with the humins, a by-product of biomass chemical conversion technologies, allow the obtention of materials with high added value. In this work, we propose a chemical connection study of humins with two aliphatic bis-epoxides through copolymerization reactions to synthesize sustainable,...

TThe need for thermosets from renewable resources is permanently increasing in order to find eco-friendly alternatives to petroleum-derived materials. Products obtained from biomass have shown to play an important role in this challenge. Here we present the structural characterization of new bio-based thermosets made by humins, a by-product of...

The present work focuses on the conception of bio-based epoxy resins arising from an increasing interest class of curing agents: the dicarboxylic acid. The hardener used was first synthesized from maleic anhydride and dipropylene glycol and then copolymerized with epoxidized linseed oil (ELO) to design resins from bio-resources. The anionic...

Bio-based thermosetting resins were synthesized from a ternary composition: humins; epoxidized linseed oil (ELO); and an industrial hardener, Capcure3-800 (CAP). Humins are in a focused attention in the last years, as biorefinery by-product, therefore its valorization through materials design is very important. Here we present a structural...

A review. This chapter highlights the main recent researches on biobased thermo-setting resins. In the last two decades, esp. the last years, many efforts were dedicated (i) to synthesize new biobased building blocks used thereafter to build thermosetting resins and/or (ii) to elaborate thermosetting resins from renewable resources. The...
