Novel degradable acetal-linkage-containing epoxy resins with high thermal stability: synthesis and application in carbon fiber-reinforced plastics
Polymer Journal, Published online: 22 November 2021; doi:10.1038/s41428-021-00585-w
Novel alcohol-derived degradable acetal-linkage-containing epoxy resins HBA–CHDMVG and HOBA–CHDMVG were synthesized. The thermal decomposition temperature of HOBA–CHDMVG was higher than 300 °C; moreover, HOBA–CHDMVG exhibited excellent Charpy impact strength. The cured HOBA–CHDMVG was completely decomposed during the hydrolysis reaction under acidic conditions, and the reaction products were soluble in a tetrahydrofuran/H2O mixed solvent. Furthermore, the carbon fibers in the carbon-fiber-reinforced plastic with a HOBA–CHDMVG matrix were recovered via the complete decomposition of HOBA–CHDMVG.Publisher URL: https://www.nature.com/articles/s41428-021-00585-w
