Toughness Improvement of Epoxy Composites Using a Kind of Environment-Friendly Bio-Based Polyester Polyol

Xinyu Shang et al.

Summary: This study synthesized a liquid bio-based polyester polyol (LLP) with flexible long chains through melt polycondensation of corn straw lignin, and compounded it with epoxy resin (EP). The results showed that the brittleness of EP composite was reduced and the bending and impact strength were increased by incorporating LLP. This work opens up new avenues for the utilization of lignin and the development of low-cost, high-performance and environmentally adaptable EP composites using renewable resources.

Preparation and properties of novel bio-based epoxy resin thermosets from lignin oligomers and cardanol

Guifeng Liu et al.

Summary: A series of lignin-based epoxy resins (LEPs) were prepared and blended with renewable epoxied cardanol glycidyl ether (ECGE), then cured with methyltetrahydrophthalic anhydride (MeTHPA) to form high-performance epoxy thermosets. The incorporation of ECGE and separation of monomer-rich fractions from lignin oligomers improved the thermal and mechanical properties of the cured products significantly. These bio-based epoxy resins show potential as renewable alternatives to BPA epoxy resins.

Preparation of carboxylated lignin-based epoxy resin with excellent mechanical properties

Yongjian Zhang et al.

Summary: By using lignin as a co-hardener, epoxy resins can be simultaneously reinforced and toughened, improving their mechanical properties. Within a certain range, the flexural strength and elongation at break of epoxy resins also increase with the addition of lignin.
