A new class of 2D materials named “MXene” has recently received significant research interest as they have demonstrated great potential for the applications in batteries, supercapacitors, and electronic devices. However, the research on their thermal properties is still very limited. In this work, Ti3C2Tx films were prepared by the vacuum-assisted filtration of delaminated nano-flake Ti3C2Tx MXenes. The thermal and electrical conductivity of the Ti3C2Tx films were measured by the state-of-the-art T-type method. The results showed that the effective thermal conductivity of the films increased from 1.26 W·m−1·K−1 at 80 K to 2.84 W·m−1·K−1 at 290 K, while the electrical conductivity remained at 12,800 Ω−1·m−1 for the same temperature range. Thermal resistance model was applied to evaluate the inherent thermal conductivity of the Ti3C2Tx flakes, which was estimated to be in the range of tens to hundreds W·m−1·K−1. View Full-Text
