Abstract: Some variations provide an anisotropic thermally conductive polymer composition comprising a plurality of polarizable, thermotropic main-chain liquid-crystal polymer molecules with crystalline domains. The liquid-crystal polymer molecules are in a nematic phase or a smectic phase, and at least 80% of the crystalline domains are aligned along a crystal axis. A method of making an anisotropic thermally conductive polymer composition comprises: synthesizing or obtaining a polymer containing polarizable domains; heating the polymer to form a polymer melt; cooling the polymer melt to form a thermotropic liquid-crystal polymer; exposing the thermotropic liquid-crystal polymer to an electrical field, thereby aligning the polarizable domains along a crystal axis; and recovering the thermotropic liquid-crystal polymer as an anisotropic thermally conductive polymer composition.
