With the development of flexible electronic devices, various requirements for flexible conductive materials have been put forward to. However, the self-healing, mechanical and conductive properties of the flexible materials are poor. Therefore, it is important to prepare self-healing materials with good mechanical and conductive properties. In this paper, room temperature self-healing and conductive composites based on imine reversible covalent bond were prepare by introducing of the carbon nanotube and carbon black. The self-healing, mechanical and conductive properties of the composites were studied. And the structure of the composites was also characterized. The experimental results showed that the mechanical strength and the electrical resistivity of composites were 6.6 MPa and 108 Omega middotm, respectively. The composites have excellent room temperature self-healing properties through the reversible exchange of imine bond, and the healing efficiency of mechanical properties and the electrical properties can reach 96% and 93%, respectively. At the same time, the self-healing mechanism was put forward to. In addition, the composites can be recovered by solution recovery and hot pressing. (c) 2021 Elsevier B.V. All rights reserved.
