چکیده
• Current review on Self-healing polymers based Diels-Alder cycloaddition. Discussing healing thermodynamics for physical and chemical changes during healing. Deeper insight use of advanced analytical/spectroscopic/modelling techniques. Use multifunctional mechanisms engineering applications. Future scope DA better commerciality green chemistry. The ability artificial materials to be healed efficiently, mimicking the living organisms, exhibits a great deal potential advantages that can revolutionise operation maintenance used in various Such self-healable smart have been extensively researched last few decades, leading development different synthesis approaches. Among these methods, techniques reversible cycloadditions or disulfide bonding provide obvious terms repeatability, which holds prime importance determining approach. This compiles recent advances field self-healing where is introduced by cycloaddition reactions while focusing mainly (DA) reactions. [4+2] reaction diene dienophile pairs are fabricate thermally crosslinked networks. These covalent bonds necessary reversibility matrix impart desired strength polymeric material. There considerable body literature has employed either its own along with other polymers. However, lack systematic discussing works makes it difficult beginner cope advancements this field. Most early studies focused stimuli efficiency but review, we would like explore governing rupture–repair process spectroscopic study them their applicability thermosets, epoxy resins, biopolymers, polymer nanocomposites. Novel applications such functional polymers, healable outlook future research, opportunities challenges area also discussed.

A Study of the Temperature Dependent Healing Capabilities of New Polymers Based on Diels-alder Cycloaddition
Because of its thermal reversibility, the retro-Diels-Alder (RDA) reaction represents an appealing possibility to produce self-healing polymers with well-defined architectures and tunable properties [1]. However, the polymer architecture for which the Diels-Alder (DA) reaction can best be used to contribute to the healing process is still not well-defined. Therefore, new terpolymers containing ...
