摘要：The preparation of carbon fiber reinforced polymers (CFRP) using vitrimer with hydroxyl ester bonds as matrix requires harsh degradation conditions. To solve this problem, tung oil-based triglycidyl ester (TOTGE) and 4-ami-nophenyl disulfide (APD) are cured to fabricate a TOTGE-APD vitrimer with a dual dynamic network of hy-droxyl ester and disulfide bonds. The TOTGE-APD vitrimer exhibits a low dynamic bond exchange activation energy (66.51 kJ/mol) due to the introduction of disulfide bonds and can achieve stress relaxation at 100 degrees C, thus exhibiting excellent self-healing and recycling properties. After crushing/remodeling, tensile strength of the remodeling sample can achieve 97.5% the original sample. Due to the disulfide and ester group in the vitrimer, CFRP prepared with TOTGE-APD vitrimer can be degraded in mercaptoehtanol, ethanolamine, and ethylene glycol, achieving multiple recycling.
