摘要：Poly(1,2,3-triazolium) (PTAM) is a kind of self-healing adhesive based on dynamic reversible covalent 1,2,3-triazolium, which is formed through the reaction of halogenated hydrocarbon and 1,2,3-triazole and plays an important role in the properties of PTAM. Therefore, it is valuable to understand the effect of halogenated hydrocarbon crosslinkers on the properties of PTAM. A series of PTAM adhesive with different crosslinkers have been prepared. The reactivity between halogenated hydrocarbon and 1,2,3-triazole was different. Crosslinkers with longer chain, iodine substituted and aromatic structure improved the adhesive property of PTAM adhesive joints, which was up to 17 MPa. The first self-healing efficiency of PTAM adhesive joints with aliphatic bromine crosslinkers reached more than 100% and the maximum cycle times of them was more than 9 before failure. The self-healing properties of PTAMs depend on the segment motion and anti-thermal oxygen aging of PTAMs. These results provide some insights for the structural design of self-healing adhesive and dynamic covalent materials.
