Metal–organic polyhedra are covalently linked by flexible polymer chains through photopolymerization, endowing the materials with enhanced processability, dispersity, and hydrostability.
MXenes, an emerging class of two-dimensional (2D) transition-metal carbide materials, have received increasing attention for their interesting physiochemical properties. For not only MXenes but also other 2D materials, delamination is a requisite step for the exploitation of their unique properties. In this work, a facile method for exfoliating Ti 3 C 2 T x MXene to nanosheets of small size with the aid of poly-(vinylpyrrolidone) (PVP) is designed, which has never been reported to our knowledge. Since both hydrophobic methylene groups and hydrophilic amide groups are provided with PVP, this method is applicable in a wide range of solvents, such as ethanol, water, and chloroform. Considering the charge detrapping and trapping behavior of 2D transitionmetal materials in PVP dielectric, a memory device with the configuration of reduced graphene oxide (rGO)/Ti 3 C 2 T x -PVP/Au is directly fabricated with these well-dispersed Ti 3 C 2 T x −PVP composites by the solution process technique. Interestingly, the resultant device exhibits a typical bistable electrical switching, ultralow switching voltage (∼0.9 V), and a nonvolatile rewritable memory effect with the function of flash. This work might pave the way of using MXenes for future data storage, which is an indispensable field nowadays. KEYWORDS: nonvolatile memory, Ti 3 C 2 T x −MXene nanosheets, poly(vinylpyrrolidone), flash, delamination
