In this study, a series of liquid crystal epoxy resins (LCEs) were synthesized via anionic ring-opening polymerization using mesogenic bifunctional epoxy monomers. The molecular design incorporated a rigid biphenyl-based core and flexible alkyl spacers, which facilitated mesophase formation and enhanced molecular orientation. The formation of liquid crystalline alignments during polymerization was confirmed by polarization optical microscopy (POM). Furthermore, the molecular alignment of cured resins was investigated using small- and wide-angle X-ray scattering (SAXS and WAXS). In particular, correlation was observed between the mesophase alignment and the thermal conductivity of the polymer network through systematic changes in the molecular structure. This study highlights the crucial role of molecular structure and mesogenic order in regulating the thermal performance of epoxy-base thermoset.
