Abstract: The aim of this study was to fabricate transparent polymers with high thermal conductivities for applications in electronic packaging. Characteristics of the inorganic filler, calcium fluoride (CaF2), and the polymer matrix were examined, and thermal conductivity was measured using a Hot Disk TPS 500 based on the transient plane source (TPS) method. Results showed that the thermal conductivity of the composites increased with CaF2 content. This study was the first to report such large thermal conductivity enhancements in highly transparent polymers.
