▎ 摘　　要

NOVELTY - Preparing graphene sieve grafted hyperbranched polyurethane self-healing adhesive comprises preparing graphene sieves (GM), modifying GM by solvothermal method with amino-azobenzene derivatives as functionalized reagents to obtain amino-functionalized graphene sieves (NGM), covalently grafting hyperbranched polyurethane (HPU) and self-healing functional group (SHG) to obtain graphene sieve grafted hyperbranched polyurethane self-healing adhesive (NGM-HPU-SHG). USE - The self-healing adhesive is useful in super capacitor or lithium/sodium ion battery (claimed). ADVANTAGE - The self-healing adhesive has excellent electrical properties and self-repairing effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene sieve grafted hyperbranched polyurethane self-healing adhesive prepared by above method.
