Higher-order-structure Formation in Liquid Crystal Epoxy Thermosets Investigated by Synchrotron Radiation–Wide-angle X-ray Diffraction

Network Formation and Physical Properties of Epoxy Resins for Future Practical Applications

“… 277 Similarly, much attention has been focused on emerging highly oriented structures and thereby increasing thermal conductivity by introducing mesogenic groups into the epoxy resins. 278 Lv et al succeeded in achieving thermal conductivity 2.5 times higher than that of the conventional epoxy resins by using a diamine with an anthraquinone backbone as a curing agent. 279 They employed four isomers with different positions of the amino groups, and demonstrated that all products formed semicrystalline domains and their thermal conductivity had a positive correlation with the mass density.…”

“…Considering the minimum thermal conductivity model (MTCM) in which the crystalline phase has a higher thermal conductivity, polymers with crystalline domains can be a candidate for a higher thermal conductive material . Similarly, much attention has been focused on emerging highly oriented structures and thereby increasing thermal conductivity by introducing mesogenic groups into the epoxy resins .

Phase-controllable topochemical polymerization of liquid crystalline epoxy according to spacer length

“…These results suggest that the LCE n samples display extensive regularity in their microstructures due to topochemical polymerization. 28,45,59…”

“…These results suggest that the LCE n samples display extensive regularity in their microstructures due to topochemical polymerization. 28,45,59 Remarkably, the patterns of LCE 4 and LCE 6 display clear, sharp peaks in the low-angle range, indicating smectic phases corresponding to the intermesogen (2θ = 5.34°, d = 16.5 Å) and the size of the mesogens (2θ = 10.7°, d = 8.3 Å). Conversely, the pattern of LCE 8 exhibits a very faint peak at around 5.32°(d = 16.6 Å), which might indicate that smectic orientation partially exists simultaneously with nematic orientation.…”

The Side‐Chain Liquid Crystalline Epoxy Polymer Grafted Nanoparticles for the Thermal and Mechanical Enhancement of Epoxy Nanocomposites

“…It is noteworthy that polymer composite materials with liquid crystal polymers can improve the mechanical property and thermal property without reducing other properties . The liquid crystal structure in the liquid crystalline polymer can be immobilized in the epoxy network structure during the curing process . In comparison with the ordinary polymer, a series of enhanced properties, such as anisotropic orientation, high modulus, and impact strength, are displayed, owing to a mass of directional ordered liquid crystal domains cured in the network when encountering the force …”
