Abstract: The authors present a method for measuring the thermal conductivity and thermal capacity of thin insulating and super-insulating materials. The new method is compared to previously existing methods and elaborates upon why these methods are unacceptable for the measurement of thin insulating materials. The researchers developed a 3D and 1D model in order to aid in the determination of thermal conductivity. The proposed method involved sandwiching a sensor/heater between two samples and measuring the heat transfer. It was determined that it is better to have two samples of different thickness than to have the two samples be identical.
