The uniqueness of liquid crystal epoxy resins (LCERs) thermoset is due to its relatively free movement of anisotropic molecules and aggregation of elongated range ordering. This leads to distinct sensitivity of LCERs to electric and magnetic fields, these initiated it profitable growth in the field of science. Here, we describe the synthesis and characterization of new twin bifunctional (LCERs) thermosets with phenyl benzoate mesogen, connected by aliphatic spacer. From differential scanning calorimetry and polarized optical microscopy investigation, the monomer exhibits stable enantiotropic nematic LC within the temperature range (115−210 °C), increasing the chain length slightly reduce the LC temperature. Considering the LC temperature range, 4,4'-diaminodiphenylmethane (DDM) was used to prepare the cured samples, and it exhibit high thermal conductivity up to 0.45 W/m·K, and the decomposition temperature of ∼350 °C with glass transition temperature (Tg) of ∼100 °C. |
