“…30 The material without thiourea (B1) turns out no self-healing process as we previous studied. 30 When the ratio of HMDI to TCDI is 6:1 (B2), it exhibits a negligible selfhealing process; the healing efficiency is only 5.6% after 24 h. The poor self-healing properties can be ascribed to the inert dynamic process of H-bonds at room temperature, which can be activated by heating 1,28 or assistance of trance organic solvent. 20 Further increase of thiourea content to 3:1 (B3) demonstrated an enhanced healing efficiency to 56.2% after 24 h. When the thiourea content increased to 1:1, the material shows a fast self-healing process; the healing efficiency reaches 100% after 10 min.…”

“…Nevertheless, these materials are usually accompanied by poor mechanical robustness because of inducing reversible dynamic crosslinking points, which restricted their further development. To obtain self-healing materials with better integrated properties, researchers came up with the design method by combining two or more types of reversible bonds in one self-healing system to enable a hierarchical energy dissipation mechanism. , For example, Lee et al prepared a self-healing PU via dual-dynamic covalent bonds containing imine and disulfide bonds. Compared with materials containing only one type of dynamic covalent bond such as imine and disulfide group, PU crosslinked with dual-dynamic covalent bonds exhibited excellent self-healing property due to the synergy of the dual-dynamic metatheses of the imine and disulfide bonds .…”

“…Currently, introducing BNNSs into polymers and simultaneously constructing its thermally conductive network in nanocomposites is an effective way. [15,17,96,[153][154][155][156][157][158] Table 2 shows the highest values reported in previous literature at the time of writing for the thermal conductivity of polymer/BNNS nanocomposites and the corresponding nanocomposite fabrication technique adopted.…”
