Eco-Friendly Furan Amines: A Step Forward in Sustainable Polymers

What is it about?

This research article investigates the synthesis of biobased polybenzoxazines from natural feedstocks, specifically hydroxymethylfurfural (HMF)-sourced carbohydrate amines and cashew nut waste-sourced renewable phenol. The study successfully synthesized a furandiamine (fda) and a benzoxazine monomer in a single step, confirming their structures through spectroscopy and mass spectrometry. The bisbenzoxazine monomer, C-fda, demonstrated a lower ring-opening polymerization temperature compared to its monobenzoxazine counterpart, C-fa. Poly(C-fda) showed superior adhesive properties in water and notable thermal performance, outperforming commercial phenol formaldehyde resins in adhesion due to additional noncovalent interactions. The article highlights the potential of furan-based precursors, especially furan amines, in designing high-performance polybenzoxazines. This work contributes to the development of sustainable polymers with enhanced properties by leveraging abundant biobased resources.
