Abstract
Liquid-crystalline epoxy (LCE) thermosets are well-known for their advancements in thermal and mechanical performance. These properties are commonly attributed to mesogenic ordering; however, the impact of molecular packing and network structure remains abstruse. In order to investigate the connection between molecular structure, network organization, and material properties, synthetic LCE monomers were cured using amine and structure-variant acid anhydrides. While evidence of LC ordering was detected in some systems, the results revealed that ordering by itself did not ensure better characteristics. Instead, the samples with enhanced performance generally showed proof of more effective molecular packing, such as increased rigidity, higher density, and improved thermal conductivity. These discoveries demonstrated that molecular packing is a key contributor to the properties of LCE thermosets and provide new insights about design principles of high-performance thermosetting materials.
