Liquid crystal epoxy resin is a highly molecularly ordered, deeply molecularly cross-linked polymer network that combines the advantages of liquid crystal alignment and network cross-linking, and its heat resistance and water resistance compared to ordinary epoxy resins. Impact resistance is greatly improved, and can be used to prepare high-performance composite materials; at the same time, the liquid crystal epoxy has small linear expansion coefficient in the orientation direction, high dielectric strength, low dielectric loss, and can be used in high-performance required electronic packages. The field is a structural and functional material with a bright future.
According to experts, PDLC (Polymer dispersed liquid crystals) substrates containing liquid crystal epoxy have a higher Tg than conventional PDLCs, and their photo-electrical performance is correspondingly improved: they have lower driving voltage, shorter switching time, and higher definition. As the temperature rises, the relaxation time decreases, which is ideal for PDLC display. However, from the perspective of performance research and development, there is no systematic report on the mechanical properties of liquid crystal epoxy resins.
The study of liquid crystal epoxy began late and is still immature. At present, the research of liquid crystal epoxy is mainly focused on the synthesis and phase characterization of the main chain liquid crystal epoxy. However, there are few studies on its reprocessing and application, especially the research on side chain liquid crystal epoxy. This will surely become a hot spot for future research. Therefore, seeking an effective way to reduce raw materials and processing costs, synthesizing and manufacturing liquid crystal epoxy with a given structure and good overall performance is bound to become a trend in the development of liquid crystal epoxy. At the same time, the use of liquid crystal epoxy resin to modify ordinary epoxy resin, is also a feasible way to achieve high performance of epoxy resin, has broad prospects and inherent potential.
With the continuous deepening and improvement of research, liquid crystal epoxy will be more widely used in various fields of the national economy.
