Highly Oriented Liquid Crystalline Epoxy Film: Robust High Thermal-Conductive Ability.

ABSTRACT: The molecular orientation effect of a liquid crystalline (LC) epoxy resin (LCER) on thermal conductivity was investigated, with the thermal conductivity depending on the surface free energy of amorphous soda-lime-silica glass substrate surfaces modified using physical surface treatments. The LC epoxy monomer was revealed to form a smectic A (SmA) phase with homeotropic alignments on the surfaces of substrates that possess high surface free energies of 71.3 and 72.7 mN m^-1, but forming a planar alignment on the surface of a substrate that possesses a relatively low surface free energy of 46.3 mN m^-1. The optical microscopy observations and the X-ray analyses revealed that the LC epoxy monomer also induced a homeotropically aligned SmA structure due to cross-linking wit
