We developed the thermal diffusivity measuring system with applying the mechanical stress to the samples, and measured the stress dependence of thermal diffusivities for various materials. We found that the thermal diffusivity of “cellulose nanopapers”, consisted of naturally derived cellulose nanofibers, clearly responded to the applied stress. This behavior is considered due to the stress response of internal structure of nanopaper, which is the intrinsic property that the other materials did not show.
