Synthesis and Properties Study of Liquid Crystalline Epoxy Resin Containing Azomethine-Based Monomeric Mesogens
The epoxy monomer N,1-bis(4-(2-oxiranemethoxy)phenyl)methylamine (HBAP-EP) was synthesized through the Schiff base reaction and epichlorohydrin method, and the HBAP-EP monomer was cured using p-aminobenzene sulfonamide (SAA). Differential scanning calorimetry (DSC), X-ray diffraction (XRD), and polarizing optical microscopy (POM) demonstrated that the epoxy monomer exhibits reversible liquid crystal properties, and the liquid crystal fraction of the monomer can reach 14.4% after curing at 120 °C. The fracture toughness of the resin cured at 120 °C can reach 0.93 KJ·m<sup>-2</sup>, and its thermal conductivity is 0.3229 W·(m·K)<sup>-1</sup>, both of which are higher than those of ordinary epoxy resin.
