Description

The limited thermal conductivity of many polymers has constrained their widespread use,despite their appeal for their resilience, affordability, and lightweight nature. Hexagonal boronnitride (h-BN), the structure analog of graphite, has many applications due to its superbproperties. Owing to its stacking layer structure, h-BN possesses anisotropic thermaltransportation property, exhibiting superior thermal conductivity along its in-plane direction butlower cross-plane thermal conductivity. Developing h-BN composites with controllable BNalignments will enable great potential for making high thermal conductive components for variousapplications. Digital light processing (DLP) is one of the additive manufacturing (AM) techniquesthat can be used to control h-BN plate orientation in a polymer matrix. This research investigatedthe DLP-printed h-BN composites, and the results showed the controllable alignments of h-BN inthe composites for improved thermal conductivities.
