Abstract:Epoxy polymer materials with furan-maleimide reversible covalent bonds were prepared by mixing different mole ratio of octylene glycidyl ether (OCG) and reversible epoxy glycidyl ether (FDB) with equivalent polyether amine (D230). The films were characterized by IR, DSC, TGA, SEM, mechanical test and OM observation. The effects of the mole ratio of OCG to FDB on properties of the epoxy polymer were investigated. The results show that the glass transition temperature of epoxy polymer decreases with increase of the mole ratio of OCG to FDB, while the tensile modulus, elongation at break and the healing property at 70 ℃ increase first and then decrease. The prepared epoxy polymer has better mechanical and healing properties. The maximum tensile modulus is (9.57±0.12) MPa, the highest elongation at break is 315.8%±3.9%, and the best healing efficiency at 70 ℃/24h is 78.86%±6.17% with the mole ratio of OCG to FDB of 1.5.
