To develop an advanced heat managing material, mesogenic monomer was newly synthesized for anisotropic heat transfer (AHT) films. As a result of spectroscopy, scattering and thermal analyses, the synthesized monomer formed a smectic A mesophase between crystalline and isotropic phases. The AHT films polymerized in meso- and isotropic phases exhibited outstanding thermal conductivity over 1 W/mK regardless of the molecular packing and orientation of mesogenic monomer. The uniaxially oriented AHT films showed outstanding thermal conductivity of 2.5 W/mK amplified along the director. The highly thermal conducting AHT films can be used as an advanced thermal managing material.
