Realizing ultra-stable Ti 3 C 2 -MXene in aqueous solution via surface grafting with ionomers

MXenes are the first class of 2D materials with the combination of metallic conductivity and hydrophilicity. However, degradation forms a key drawback limiting their long-term applications. This work for the first time demonstrates a strategy for designing a hydrophilic yet ultra-stable MXene via surface grafting with ionomers.
