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-phenylphenothiazine (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).

在该手稿中，通过将表面引发的光诱导电子转移-原子转移自由基聚合（PET-ATRP）与贻贝启发的化学方法相结合，成功制备了可自修复的纳米复合水凝胶。使用这些有效且环保的方法，通过以聚多巴胺（PDA）为锚点和10-苯基吩噻嗪（PhPTZ）为有机物的PET-ATRP，在氧化石墨烯（GO）的表面上引发了聚（4-乙烯基吡啶）（P4VP）光催化剂。后原位丙烯酸的聚合，成功获得自愈纳米复合水凝胶，并且他们有优良的拉伸强度（约6.94兆帕），韧性（605％）的性能以及自我修复效率（8小时后94.9％） 。
