Achieving high lignin content and mechanical enhancement in biobased thermosets via a high-molecular-weight soybean oil skeleton

Key Points

• The aim is to develop sustainable thermosets with high lignin content that can match petroleum-based options.
• Utilized high-molecular-weight soybean oil as a base for thermosets.
• Investigated lignin incorporation rates and mechanical properties through systematic testing.
• Measured performance outcomes compared to conventional thermoset materials.
• Achieved significantly higher lignin content in thermosets, enhancing mechanical properties.
• Mechanical tests showed improved strength with the biobased thermosets compared to traditional composites.
• Indicated potential for biobased materials to substitute petroleum-derived thermosets.
