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 ...
The focus of this research was to discover new thermally conductive ceramic/plastic composites for their use in thermal management. In this experiment, the thermal constants analyzer was used to measure the thermal conductivity of composite films containing hexagonal boron nitride particles and polyimide. Upon testing, a thermal conductivity of 7 W/mK with a 60% filler content was noted, as compared to a thermal conductivity of 5 W/mK for the plastic ...
