Herein, we introduce a TMD-based antioxidation platform having excellent radical scavenging performance as well as structural stability under harsh storage conditions. The key to this approach is to fabricate a stable suspension of TMD nanosheets with an ultrathin platelet configuration that exhibits the defect-mediated one-step hydrogen atom transfer (HAT). Accordingly, we fabricated the stable suspension of TMD nanosheet by enveloping them with a monolayer of an amphiphilic diblock copolymer, poly(ε-caprolactone)-b-poly(ethylene oxide) (PCL-b-PEO). We subsequently characterized the optical and structural properties of PCL-b-PEO-enveloped TMD nanosheets. Finally, we demonstrated that the TMD nanosheets fabricated in our study showed outstanding radical scavenging activities in aqueous media by using (2,2′-azino-bis(3-ethylben-zthiazoline-6-sufonic acid) (ABTS) assay under a variety of storage conditions. |
