Abstract
Thermosetting polymers are widely used as high-performance matrices in structural, electronic, and aerospace composites; however, their amorphous and permanently cross-linked nature often limits molecular organization, thermal transport, and recyclability. Liquid crystalline thermosets (LCTs) overcome these limitations by integrating ordered mesogenic structures into robust cross-linked networks. These molecularly ordered systems exhibit enhanced thermal conductivity, anisotropic properties, high thermal stability, and tunable mechanical performance while retaining the dimensional reliability of conventional thermosets.
This presentation focuses on the molecular design and functionalization of LCTs for advanced composite applications. Specifically, the effects of mesogenic structure, spacer length, curing chemistry, and network topology on liquid crystalline ordering and macroscopic properties will be highlighted. Furthermore, incorporating dynamic covalent bonds into LCT networks enables reprocessability and topological rearrangement, providing a promising pathway toward sustainable, high-performance materials. Ultimately, these results demonstrate that LCTs serve not merely as structural matrices, but as versatile molecular platforms for designing next-generation functional composites featuring superior thermal management, mechanical reliability, and circularity.
