US 2023/0123580 A1 · COMPOSITE BODY HAVING HIGH THERMAL CONDUCTIVITY AND METHOD OF MAKING THE COMPOSITE BODY

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 40 vol % to 90 vol % based on a total volume of the body; and the body comprises an in plane thermal conductivity of at least 15 W/mK. The hBN particles within the composite body can have a March-Dollase Orientation parameter η of at least 50%.
