“…Yang et al 39 prepared self‐healing mBN/thiol‐epoxy elastomer composites based on thiol‐epoxide reaction, as the loading of mBN fillers is 60 wt%, the composites presented a high optimal thermal conductivity ( λ ~1.058 W mK −1 ), excellent self‐healing efficiency of ~85% as well as a high tensile strength after self‐healing. However, although the above reports can obtain high‐strength and high healing effect, their mechanical strengths are always less than 10 MPa, especially via heat directly 40‐44 . That is, self‐healing polymer composites have still absented real high‐strength so far.…”

“…What's more, healing progress still need a long time to repair the damaged composites based on D‐A reaction. In additional, in order to decrease healing progress, some strategies including adding carbon back, 45 CNTs, 46 graphite, 47 graphene, 42 graphene oxide 48 and carbon black 49 have been also reported. For instance, Li et al 42 synthesized a polymer/graphene based self‐healing material with a cross‐linking network structure via D‐A reaction.…”

For instance, Li et al 42 synthesized a polymer/graphene based self‐healing material with a cross‐linking network structure via D‐A reaction. As FGO loadings is 5 wt%, self‐healing efficiency of 90% were obtained under healing by heat at 110°C for 60 s; Guo et al 50 prepared self‐healing and recyclable carbon tube/epoxy adhesive.…”

Polymer composites with self‐healing ability are highly desired for applications in advanced modern devices. Here, we report on self‐healing polymer composites consisting of silver deposited‐carbon nanotubes hybrid nanoparticles (CNT‐Ag) as fillers and self‐healable polyurethane (DAPU) as a matrix based on thermally reversible Diels‐Alder reaction. The results indicated that as the hybrid filler loading is 1 wt%, the composites not only obtained a high‐strength (~15.97 MPa) and high healing efficiency (~90.1%) by increasing filler loading after healing, but also enhance thermal conductivity (~1.65 Wm−1 K−1) and obviously shorten its healing progress in comparison with other composites in the case of the same healing time. Given that Ag_NPs deposited on the surfaces of the CNTs act as bridges to link the adjacent CNTs and reduce interfacial thermal resistance, which can effectively explain the reasons for the obtained high mechanical strength and healing efficiency and promoting healing progress in the polymer composites. This work may offer a novel strategy for balancing relation between mechanical property, healing ability and healing progress in the field of self‐healing materials application.

“…For example, conductivity is greatly required for electronic applications such as microelectronics packaging [33], medical devices [34], artificial skins [35], and electromagnetic interference (EMI) shielding [36]. So far, several research studies have been performed to develop DA based nanocomposites, wherein conductive fillers such as metallic nanoparticles [37], carbon nanotubes [38,39,40], and graphene [41,42,43] were incorporated into the material systems. In particular, graphene has attracted a great interest because this two-dimensional carbon allotrope possesses large aspect ratio as well as superior carrier mobility, and can thereby serve as a promising material in EMI shielding technology [43,44,45].…”

In this study, a novel biobased poly(ethylene brassylate)-poly(furfuryl glycidyl ether) copolymer (PEBF) copolymer was synthesized and applied as a structure-directing template to incorporate graphene and 1,1′-(methylenedi-4,1-phenylene)bismaleimide (BMI) to fabricate a series of self-healing organic/inorganic hybrid materials. This ternary material system provided different types of diene/dienophile pairs from the furan/maleimide, graphene/furan, and graphene/maleimide combinations to build a crosslinked network via multiple Diels–Alder (DA) reactions and synergistically co-assembled graphene sheets into the polymeric matrix with a uniform dispersibility. The PEBF/graphene/BMI hybrid system possessed an efficient self-repairability for healing structural defects and an electromagnetic interference shielding ability in the Ku-band frequency range. We believe that the development of the biobased self-healing hybrid system provides a promising direction for the creation of a new class of materials with the advantages of environmental friendliness as well as durability, and shows potential for use in advanced electromagnetic applications.

“…This is typically accomplished by physical interaction or chemical interaction, as sketched in Figure 1. Most intrinsic recovery designs rely upon either reversible covalent bonds, such as Diels‐Alder reactions, [2–12] disulfide bonds, [13–17] boronate ester bonds, [18–21] and imine bonds, [22–24] or non‐covalent, including hydrogen bonds, [25–32] ionic, [33–37] and hydrophobic interactions, [38–40] host‐guest interactions, [41–45] π‐π stacking, [46–48] and metal coordination [49–54] or supramolecular chemistry.…”
