The measurement method is based on the Patent of ITL Inc. Scientists “Method of Measurement of Thermal Conductivity of Thin Rods”. [1]. Thermal conductivity of nano particles is determined based on the mathematical models of apparent thermal conductivity of mixture of the particles with liquid (ie. heptane, decane)
Example of our data at the range -100°C to +20°C is submitted on the picture.
