中文摘要: 高折射率光学材料是先进光电领域内的热点研究课题。本申请课题拟对高折射率(折射率>1.71)的环硫树脂光学材料进行深入系统的研究。从分子水平上设计上述聚合物的化学结构。通过将噻蒽以及硫醚等高摩尔折射率基团引入环硫树脂的分子结构中,进一步提高其折射率,同时兼顾材料的阿贝数、光学透明性、耐热稳定性能以及机械性能。在系统研究噻蒽、不同硫醚等含硫基团对环硫树脂综合性能影响规律的基础上,掌握环硫树脂的化学制备技术,为未来研制开发先进高折射率光电材料提供理论依据与基础数据。

英文摘要: High refractive index optical material has become a research hotspot in advanced photoelectric fields. This research is to systematically study the high refractive index (n>1.71) episulfide-type optical resins. The molecular structures of the episulfide-type optical resins have been designed from the molecular level. By incorporation of the high molar refractive groups, i.e. thianthrene-containing groups and thioether, into the molecular structures of episulfides to improve their refractive indices, at the same time, the Abbe's nummber, transparency, heat resistance and mechanical properties are also considered. Systematically study the influence of thianthrene-containing groups and different thioether groups on the overall properties of episulfides, master the synthesis techniques of episulfides, provide theoretical basis and fundamental data for future development of advanced high refractive index photoelectric material.
