Analysis of thermal radiation properties of polyimide and polymeric materials based on ATR-IR spectroscopy

Abstract

A facile and non-distractive method for estimating thermal emissivity of solid polymers based on ATR-FT-IR method was newly developed. This method is applicable to thick and nontransparent samples without using blackbody furnace. The thermal emissivity estimated by this method is consistent with the reference values obtained using blackbody furnace. The ATR-IR method enables to estimate thermal emissivity of polymer materials having arbitrary shapes not only bulk and films but also forms and fabrics.
