The present disclosure relates to a high thermal conductive polymer composite, comprising: a liquid crystalline resin comprising a mesogen and at least one linear polymerization reactive group, wherein the liquid crystalline resin is cured with a linear polymerization initiator and includes a molecular structure aligned in at least one direction.

Composites with enhanced thermal conductivity and method preparing the same

Disclosed is a method of purifying boron nitride nanotubes through a simplified process. Specifically, the method includes preparing a starting solution containing boron nitride nanotubes (BNNTs), a dispersant and a solvent, centrifuging the starting solution or allowing the starting solution to stand to collect a supernatant, adding an acid to the supernatant and filtering a resulting product.

Disclosed is a liquid crystalline epoxy compound wherein an epoxy group is positioned at a side chain of the longer direction of a mesogen group and each of the mesogen group and the epoxy group is connected to the center of the molecular structure through a flexible linkage. Since the liquid crystalline epoxy compound includes an epoxy group positioned at a side chain of the longer direction of a mesogen group and each of the mesogen group and the epoxy group is connected to the center of the molecular structure through a flexible linkage, the interaction between the mesogens in a cured resin product occurs significantly without weakening even after curing, thereby improving the heat conductivity of the resin compound through the active heat transfer between the mesogens.
