Self-healing by Diels-Alder cycloaddition in advanced functional polymers: A review

Controlled Synthesis of a Homopolymer Network Using a Well-Defined Single-Component Diels–Alder Cyclopentadiene Monomer

“…This approach realized the feasible processability of Cp-based homopolymers, subsequently enabling characterization studies and post-damage (i.e., self-healing) repair strategies. Besides the prominent reports of homopolymer networks, more strategies have been applied to generate Cp groups in situ via postfunctionalization or pair it with a highly reactive dienophile, such as cyanodithioester (CDTE). ,, For example, Kennedy and Castner reported the incorporation of pendant Cp units by cyclopentadienylation with chlorinated butyl rubber polymers. In situ dimerization of Cp leads to the formation of reversible networks .…”

Repetitive self-healing of Diels–Alder grafted graphene nanoplatelet reinforced carbon fiber reinforced polymer composites with outstanding mechanical properties

“…However, in their work, the interfacial healing capability after the incorporation of DA-grafted graphene nano-filler in a polymer matrix was not explored. In a recent review work reported by Ratwani et al 25 on DA-adduct grafted self-healing polymer systems, it was reported that DPMBMI-Carbon nanotubes show 103.4% healing with 2.12 MPa shear modulus; EpF-Multiwalled CNTs show 79.82% healing with 70.3 MPa tensile strength; FGE-DPMBMI-GNS shows 85% healing with 14.52 MPa tensile modulus; MWCNTs/ DA-epoxy shows 77% healing with 22.1 MPa tensile strength and our previous work on B-GNPs in HPM shows 87% healing with 5.63 MPa tensile strength.…”

Dynamic and mechanically robust and ultrafast healable ionogel for nerve fiber-inspired signal transmitter

“…Heating lacks good spatial controllability and UV irradiation is not a mild condition. 25,26 Furthermore, covalent self-healing usually has slow healing speed (typically taking hours to days), [27][28][29] which may cause the long-term failure of electronics.…”
