Empirical Two Step Approximation for Characterizing Thermal Properties of Ultrathin Graphite Sheet

摘要

The estimation method for unknown thermal properties of ultrathin graphite sheet is suggested in this work. Based on the well known thermal properties of a few materials, the estimation was done by two step approximation algorism. The experimental measurement for tour materials of copper, aluminum, indium and graphite was performed at the restricted laboratory environment to get the mutual relation indicating special regularity between those materials. The estimated value of thermal conductivity for a graphite ultrathin thermal sheet was 646 W/m-K that was reasonable comparing to its functional capacity.
