In this study, optical diffusers based on epoxy resin/thiol/nematic liquid crystal composites were prepared using different curing temperatures, curing times and curing agents (thiols). Additionally, the effects of the curing temperatures, the curing times and the thiols on the polymer ball microstructures and the optical properties of optical diffusers were investigated systematically. For applications of optical diffusers, the optimized curing temperature has been achieved by combining the high transmittance and high haze. A novel optical diffuser with ultrahigh transmittance (>94.0%), ultrahigh haze (>94.0%) and excellent diffusing ability has been obtained, of which the polymer morphology is single polymer micro-balls without aggregation.
在本研究中，基于环氧树脂/硫醇/向列型液晶复合材料的光学漫射器通过使用不同的固化温度、固化时间和固化剂（硫醇）制备而成。此外，还系统研究了固化温度、固化时间和硫醇对聚合物球微观结构以及光学漫射器光学性能的影响。对于光学漫射器的应用，通过结合高透光率和高雾度实现了优化的固化温度。已获得一种具有超高透光率（>94.0%）、超高雾度（>94.0%）和优异漫射能力的新型光学漫射器，其聚合物形态为无聚集的单一聚合物微球。
