To develop an enhanced heat dissipating materials which can manage the heat in the various industries, high thermal conducting property is required. In this research, two type discotic reactive mesogens containing the triphenylene were synthesized for advanced heat transfer materials. Each monomers have vinyl and thiol functional groups for cross-linking. Based on the combined techniques of scattering, and thermal analyses, it was confirmed that the mixture formed the isotropic structure and liquid crystal structure coexist. The mixture was polymerization by irradiating UV light for 1 h. The polymer film shows thermal conductivity up to 1.09 W/mK, this value is higher than other heat transfer organic materials. Due to ordered lattice structure of monomer core, the film exhibited excellent heat transfer property.
