AI Article Synopsis

  • Sustainable production of polymers from renewable sources, like biomass, is crucial to tackle climate and environmental issues.
  • The study introduces an all-biobased curable resin made from materials such as fumaric acid and 2,5-furandicarboxylic acid, created without solvents for better industrial use.
  • This new biobased resin shows strong thermal stability, high resistance to deformation, and good chemical resistance, making it promising for various industrial applications.

Article Abstract

The sustainable production of polymers and materials derived from renewable feedstocks such as biomass is vital to addressing the current climate and environmental challenges. In particular, finding a replacement for current widely used curable resins containing undesired components with both health and environmental issues, such as bisphenol-A and styrene, is of great interest and vital for a sustainable society. In this work, we disclose the preparation and fabrication of an all-biobased curable resin. The devised resin consists of a polyester component based on fumaric acid, itaconic acid, 2,5-furandicarboxylic acid, 1,4-butanediol, and reactive diluents acting as both solvents and viscosity enhancers. Importantly, the complete process was performed solvent-free, thus promoting its industrial applications. The cured biobased resin demonstrates very good thermal properties (stable up to 415 °C), the ability to resist deformation based on the high Young's modulus of ∼775 MPa, and chemical resistance based on the swelling index and gel content. We envision the disclosed biobased resin having tailorable properties suitable for industrial applications.
