“…Earlier works in self-healable polymer composites excluded such TMD nanosheets from the healing process [16] or employed alternative healing chemistry. [17] Meanwhile, functionalization attempts for TMDs focused on thiol-ligand conjugation and showed that TMDs, like MoS 2, can be functionalized in the presence of thiols to fill the basal-plane sulfur vacancies and impart bonding sites from the reduced disulfide bonds. [18] This suggests that the simple techniques conventionally used for graphene oxide functionalization can also be used for TMDs, and sulfur vacancies can be substituted by thiol-ligand conjugation.…”

Nanocomposites with enhanced mechanical properties and efficient self‐healing characteristics can change how the artificially engineered materials’ life cycle is perceived. Improved adhesion of nanomaterials with the host matrix can drastically improve the structural properties and confer the material with repeatable bonding/debonding capabilities. In this work, exfoliated 2H‐WS2 nanosheets are modified using an organic thiol to impart hydrogen bonding sites on the otherwise inert nanosheets by surface functionalization. These modified nanosheets are incorporated within the PVA hydrogel matrix and analyzed for their contribution to the composite's intrinsic self‐healing and mechanical strength. The resulting hydrogel forms a highly flexible macrostructure with an impressive enhancement in mechanical properties and a very high autonomous healing efficiency of 89.92%. Interesting changes in the surface properties after functionalization show that such modification is highly suitable for water‐based polymeric systems. Probing into the healing mechanism using advanced spectroscopic techniques reveals the formation of a stable cyclic structure on the surface of nanosheets, mainly responsible for the improved healing response. This work opens an avenue toward the development of self‐healing nanocomposites where chemically inert nanoparticles participate in the healing network rather than just mechanically reinforcing the matrix by slender adhesion.

Comprehensive SummaryIn recent years, flexible photodetectors (FPDs) have received increasing attention due to their applications in electronic eyes, flexible sensing, terminal devices, and wearable devices. In addition, metallic halide perovskite materials are considered as future materials for FPDs due to their compatibility with flexible substrates, low cost, simple synthesis methods, and superior optoelectronic properties. This review provides a comprehensive overview of the relevant cutting‐edge research in the field of flexible perovskite photodetectors (FPPDs) from 2020 to 2022. First, the evaluation criteria for FPPDs are discussed and the development of perovskite stability criteria is emphatically described. Afterwards, the synthesis methods and device construction processes of metal halide perovskite materials commonly used by researchers in the past three years were described. These include single crystals and low‐dimensional materials. Moreover, we have elaborated on the research of self‐powered FPPD and its contributions in wearability, terminals, and portability. Finally, a summary of developments and possibilities in the field of FPPDs from 2020 to 2022 is provided.This article is protected by copyright. All rights reserved.
