摘要: The effect of the molecular orientation direction a polymer matrix on in-plane thermal conductivity (TC) injection-molded polymer/hexagonal boron nitride (h-BN) composites is investigated. In this system, h-BN platelets align in owing to injection shear flow. Three orientations (perpendicular, random, and parallel plane) are achieved using liquid crystalline polyesters TCs compared. Although chains provides highest TC direction, lowest three systems for orientation. found perpendicularly oriented irrespective direction. These results reveal that serve as effective heat paths between arranged one above other, consequently, continuous network created © 2013 Wiley Periodicals, Inc. J. Appl. Polym.
