As electronics get smaller and more powerful, the packaging that contains them must in turn become lighter with higher thermal conductivity and electrical resistivity. This study tested the effect of adding highly concentrated hexagonal boron nitride (hBN) fibers to liquid crystal polymer. The fibers were oriented in a way to achieve a high filler concentration, and the composites were then randomly added to a polyactide matrix. The researchers found that ...
Adding conductive fillers to polymer resins improves the thermal conductivity of the polymers. In this study, Thermocarb TC-300 synthetic graphite and Fortafil 243 carbon fiber were added to Vectra A950RX liquid crystal polymer (LCP) to produce anisotropic single and multiple filler composites. A Thermal Constants Analyzer measured the thermal conductivity of the composites using the transient plane source (TPS) technique. The formulations that contained Thermocarb fillers had higher in- and ...
