Epoxy resins are presently important organic matries in industry such as epoxy molding compound, electronic devices and transportation. They are used in many applications due to mechanical properties, good thermal stability, chemical resistance and higher moisture resistance. When they are the polymerization of epoxy resin, 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, compared with the existing three-dimensional network structure of the epoxy resins. By reducing the scattering of phonon, they improve the thermal conductivity of the epoxy resins. Also, The structure of graphene can form π-π stacking with LCE and more improve the thermal conductivity of LCE. This study shows synthesis of liquid crystalline epoxy and thermal properties of graphene-LCE composite. |
