Abstract: The present disclosure discloses a method for recycling a residue from MXene preparation, including the following steps: recovering a bottom residual sediment produced in preparation of MXene through etching in a minimally intensive layer delamination (MILD) method, mixing the bottom residual sediment with a molten polyvinyl alcohol (PVA) solution, and drying to prepare a Ti3C2Tx-Ti3AlC2/PVA composite film. The present disclosure can effectively utilize a residue from an MXene process to prepare a composite film with both excellent mechanical properties and electrical conductivity. The composite film has extremely-high sensitivity for stress-strain and prominent stability, and is suitable for flexible connection and sensing of biosensors, robots, or the like. The present disclosure has significant economic and environmental benefits, and is suitable for promotion and application.
