In this work, we reported a kind of electrical insulating, highly through-plane thermally conductive polyolefin elastomer (POE)-based composites filled with commercial boron nitride (BN) fabricated by a conventional melt-mixing method of two-roll milling, followed by hot compression and mechanical cutting. The as-fabricated composites with BN flakes perfectly aligning vertically in the matrix revealed high through-plane thermal conductivity (6.94 W m(-1) K-1 at a BN content of 43.75 vol%), outstanding electrical insulation (4.34x omega cm at a BN content of 43.75 vol%), and quite good mechanical properties. This fabrication procedure features facile process, industrial equipment, and easy industrialization, and the as-prepared composites with outstanding comprehensive performance are promising for thermal interface materials (TIMs) application.
