Shen, Wenbo published the artcileElectrically switchable light transmittance of epoxy-mercaptan polymer/nematic liquid crystal composites with controllable microstructures, Product Details of C17H28O8S4, the main research area is epoxy resin mercaptan nematic liquid crystal composite light transmittance; electrooptical property.

In this paper, we report the design, preparation and properties of epoxy-mercaptan polymer/nematic liquid crystal (LC) composites with elec. switchable optical transmittance. It is found that the polymer microstructure can be regulated from porous structure to microspheres or beads by appropriately modulating the curing temperature, the mol. structure of mercaptan, as well as the compositions of epoxy, mercaptan and nematic LC host. Under an external elec. field, the thin films based on such composites can switch from opaque to transparent. The electro-optical performance is found to be highly dependent on the polymer microstructures and the optimum characteristics can be achieved in the composite with a microstructure of smaller microspheres. The possible mechanism for the formation of polymer microspheres and the effects of the microstructures on the electro-optical characteristics of the composites are also discussed. This work is expected to provide an efficient way to control the microstructure of epoxy/mercaptan polymer and develop the composites with switchable optical transmittances for both civil and military applications.
