Abstract
A composite article can comprise a composite body including an organic polymer and ceramic particles comprising hexagonal boron nitride (hBN) particles distributed throughout the organic polymer, wherein an amount of the hBN particles ranges from 20 vol % to 40 vol % based on a total volume of the body; and the body comprises an in plane thermal conductivity of at least 10 W/mK. The hBN particles within the composite body can have a March-Dollase Orientation parameter η of at least 50%.
