▎ 摘　　要

In this manuscript, self-healable nanocomposite hydrogels were successfully fabricated by combining surface-initiated photoinduced electron transfer-atom transfer radical polymerization (PET-ATRP) with mussel-inspired chemistry. Using these efficient and eco-friendly methods, poly(4-vinylpyridine) (P4VP) was initiated on the surface of graphene oxide (GO) via PET-ATRP with polydopamine (PDA) as the anchor and 10-phenylphe-nothiazine (PhPTZ) as organic photocatalyst, respectively. After in-situ polymerization of acrylic acid, self-healing nanocomposite hydrogels were successfully obtained, and they had excellent tensile strength (about 6.94 MPa), toughness (605%) performance as well as self-healing efficiency (94.9% after 8 h).
