Outline of Final Research Achievements

The aim of this study is to clarify the thermal conductivity and thermal effusivity of a shape memory gel by using a thermal probe with instantaneous point contact. This tool, called a thermophysical handy tester, enables in situ measurement in the short term, and can measure both the thermal conductivity and thermal effusivity of specimens. With these thermophysical properties in hand, the specific heat capacity and thermal diffusivity can be calculated from the definitional equations. The present measuremets showed that the thermal conductivity and thermal effusivity of the shape memory gel with water content of 17 % were almost identical to those of a fluorocarbon resin. Furthermore, the thermal conductivity and thermal effusivity of the shape memory gel with water content of 40 % were 1.48- and 1.09-fold greater than those of the shape memory gel with water content of 17 %.
