제목 Directional Thermal Conducting Properties of Uniaxially Aligned Liquid Crystal Polymer
초록 Polymerizable liquid crystal (LC) monomer exhibiting smectic A (SmA) mesophase was synthesized for the development of anisotropic thermal conducting materials. As a mesogenic core structure, 2-phenylnaphthalene was selected due to its highly ordered atomic lattice structures which induces the promoted phonon transfer. Using the LC monomer, thermal conducting polymeric materials were successfully fabricated. The fabricated LC polymers exhibit high thermal conductivity up to 1.21 W/mK. The orientational order of LC molecule was adjusted by polymerization under magnetic field. The uniaxially aligned LC polymer shows enhanced thermal conductivity value of 2.5 W/mK along the long axis of LC mesogen.
