MXenes produced by Lewis acid molten salt (LAMS) etching of MAX phases have attracted the community's attention due to their controllable surface chemistry. However, delamination is challenging hydrophobicity multilayer MXene and strong interactions between halogen-terminated sheets. The current method involves dangerous chemicals such as n-butyllithium or sodium hydride, making scale-up difficult limiting practical application this class MXenes. In work, we present a simple efficient for from LAMS synthesis while maintaining LiCl anhydrous polar organic solvents are used delamination. Films delaminated flexible an electrical conductivity 8000 S/cm, which maintained after week exposure 95% humidity. This successful delamination, preservation inherent properties, stability under high-humidity conditions dramatically expand range chemistries available research potential applications.
