Abstract

The emerging biomass-based epoxy vitrimers hold great potential to fulfill the requirements for sustainable development of society.Since the existence of dynamic chemical bonds in vitrimers often reduces both the thermal and mechanical properties of epoxy resins,it is challenging to produce recyclable epoxy vitrimers with both excellent mechanical properties and good thermal stability.Herein,a monomer 4-(((5-(hydroxymethyl)furan-2-yl)methylene)amino)phenol(FCN)containing furan ring with potential to form high density of hydrogen bonding among repeating units is designed and copolymerized with glycerol triglycidyl ether to yield epoxy resin(FCN-GTE),which intrinsically has dual hydrogen bond networks,dynamic imine structure and resultant high performance.Importantly,as compared to the BPA-GTE,the FCN-GTE exhibits significantly improved mechanical properties owing to the increased density of hydrogen bond network and physical crosslinking interaction.Furthermore,density functional theory(DFT)calculation and in situ FTIR analysis is conducted to decipher the formation mechanism of hydrogen bond network.In addition,the FCN-GTE possesses superior UV shielding,chemical degradation,and recyclability because of the existence of abundant imine bonds.Notably,the FCN-GTE-based carbon fiber composites could be completely recycled in an amine solution.This study provides a facile strategy for synthesizing recyclable biomass-based high-performance epoxy vitrimers and carbon fiber composites.
