| 英文摘要 | Thermal diffusivity can be measured by the laser flash method. Previous study showed that Cu2S has extremely low thermal diffusivity during the first-order phase transition. However, when laser is applied on the measured sample, both the absorption/emission of light and the increase of temperature on the measured sample will occur. Their effects on the measurement accuracy of the thermal diffusivity during the phase transition have not been investigated yet. In this study, it is found that the absorption/emission of light has neglectable influence on the thermal diffusivity measurement of Cu2S. However, the increase of temperature can significantly influence the measurement results and shift the temperature when the thermal diffusivity of Cu2S starts to decrease below the starting temperature of the phase transition determined by DSC. This can be solved by building a Cu2S/graphite double-layer structure via using the graphite to absorb part of the laser's energy. Furthermore, a thermal transport model is developed to extract the real thermal diffusivity from the measured thermal diffusivity of the Cu2S/graphite double-layer structure. This work is meaningful for accurate characterization and understanding of the thermal diffusivity of phase transition materials, photosensitive materials, and heat sensitive materials. |
