The newly designed and synthesized phenylnaphthalene-based rod-shaped monomer (RSM) has highly ordered carbon lattice structure resulting in its excellent heat transfer properties. On the basis of spectroscopy, microscopy, and thermal analysis results, RSM exhibited a smectic A mesophase. The photopolymerization of RSM in mesophase and isotropic phases was conducted to form a thermal conducting network. The thermal conductivity of polymer films was over 1 W/mK regardless of the molecular packing and orientation of RMM and anisotropic thermal conductivity was estimated to be 2.5 W/mK. The RSM polymeric films can be used in advanced thermal management materials. This work was supported by BK21 FOUR program and Creative Materials Discovery Program (2020M3D1A2100779). |
