摘要：Conventional glass fiber reinforced composites (GFRCs) are usually difficult to degrade and the matrix usually exhibit low Tg. To address this dilemma, a degradable catalyst-free self-healing vitrimer matrix with a high Tg was fabricated using turpentine-derived terpene maleic acid (TMA) as a curing agent and epoxidized menthane diamine (EMDA) with a tertiary amine structure as an epoxy resin. Due to the introduction of a rigid terpene ring skeleton of turpentine, EMDA-TMA vitrimer exhibits a Tg of up to 201.8 degrees C. Due to the tertiary amine groups in the EMDA-TMA, the vitrimer can achieve self-healing and recycling properties by dynamic transesterification reaction without the addition of catalysts. More importantly, the EMDA-TMA-GF composite prepared using EMDA-TMA vitrimer as a matrix also shows a high Tg (223.6 degrees C), and excellent mechanical properties. In addition, under the synergistic action of potassium hydroxide (KOH) and ethanolamine (EA), the EMDA-TMA-GF composite can be rapidly degraded by a KOH/EA solution to realize non-destructive recovery of glass fibers.
