Photothermal effect has been widely used in many areas such as cancer therapy, photothermal energy harvesting, and laser ignition. However, exploring reliable and efficient free‐standing energy converter for enhancing the photothermal performance is still a challenge. Herein, free‐standing membrane based on two‐dimensional MXene (Ti 3 C 2 ) nanosheets and polytetrafluoroethylene (PTFE) was fabricated and characterized by X‐ray diffraction, scanning electron microscopy and differential scanning calorimetry, which demonstrated a drastic temperature rise by laser irradiation and was further used as energy converter for enhancing the photothermal performance of laser ignition. Furthermore, the initiating power of the laser initiator can be largely reduced by adding a thin layer of MXene/PTFE membrane above the B/KNO 3 cylinder. This work can give great promise for MXene‐based membranes as the laser energy converter for reducing the initiating energy and promote the development of laser initiators with low initiating energy.
