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

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.
