Epoxy resins are used in many applications due to good mechanical properties, thermal stability and chemical resistance. The mesogenic groups of epoxy make the high ordered structure by π-π stacking. The high ordered structure makes high crystallinity in the epoxy matrix. The high crystallinity of the liquid crystalline epoxy (LCE) can reduce the phonon scattering. By reducing the scattering of phonon, they improve properties of epoxy such as thermal conductivity and electrical conductivity. Graphene nanopate(GNP), which forms π-π stacking with LCE, can improve thermal properties of LCE. Also, Carbon nanotube(CNT) with lower electrical percolation threshold compared to GNP can improve electical properites. this study shows the thermal and electrical properties of LCE by comparing the structure of LCEs and the type of fillers.
