Parametric Study on the Effect of Radiation Heat Loss and Non-Constant Heating in the Electrothermal Technique for Thermal Property Measurement of Micro/Nanoscale Fibers

摘要

This paper presents a parametric study of the effects of radiation heat loss and non-constant heating power on the measurement accuracy of thermal properties of micro/nanoscale fibers using the Transient Electrothermal (TET) technique. Measurement deviation was found to have linear relationships to both the radiation loss and the non-constant heat generation. For practical use, an experimental designer/user can estimate the error associated with these sources from the resulting diagrams. The findings of this study are beneficial for the accurate measurement of thermal properties of micro/nanoscale filament-like samples, including electrical conductors and nonconductors. These results are especially important in' the current development of synthetic spider silk for quantifying and improving its thermal properties.
