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　Ω·m,　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.　©　2021　Elsevier　B.V.
