摘　　要：高折射率环氧光学树脂设计制备方法主要包括三类:通过有机或无机化合物在环氧光学树脂中引入硫、卤素等高折光指数原子;在环氧光学树脂中引入芳环等高折光指数化学基团;由两种或两种以上的环氧树脂混合固化来制备复合型环氧光学树脂.现有的环氧光学树脂具有收缩率低、化学性质稳定、尺寸稳定性高等优点,但耐候性差,在紫外光的照射下会发黄降解,韧性差而易断裂,硬度不佳在树脂表面易产生划痕等缺点制约了其在更先进领域的应用.制约环氧光学树脂发展的主要因素为材料结构与性能之间的关系不够明确,制备方法不够经济环保以及过于关注材料的折光指数而对其他性能研究较少.进一步明确材料结构与性能之间的关系,在保证高折射率的前提下,平衡材料的其他光学和力学性能是未来研究的重点.There are three types of methods to design and prepare epoxy optical resins with high refractive index： epoxy optical resins are prepared by organic or inorganic compounds containing high refractive index atoms such as sulfur and halogen, or by compounds with high refractive index chemical groups such as aryl; composite epoxy optical resins are prepared by mixing two or more of the epoxy resins. The existing epoxy optical resins have advantages of low shrinkage, great chemical resistance and dimensional stability, but their brittle nature, low hardness, weather resistance and degradation under ultraviolet restrict their application in some advanced fields. The factors which restrict develop- ment of the epoxy optical resins are not completely clear relationship between structures and properties, uneconomic and unfriendly preparation methods for environment and too much research on the materials＇ refractive index but too little on other properties. Thus, the study of getting the balance between other optical properties and mechanical properties of the materials upon the high refractive index should be paid more attention in the future.
