纳米微粒的表面修饰与聚合物杂化光学材料的高性能化

Surface Modulation of Inorganic Nanoparticles and High Performance for the Resulting Polymer Hybrid Optical Materials

高折射率材料在很多光学仪器、光电器件以及信息储存和传导等领域均具有广泛的实际应用价值,备受科研工作者们的关注。但是由于传统光学树脂折射率可调范围小,一般低于1.80,使其逐渐不能满足当代社会对器件微型化的要求。笔者研究组近十年来,通过将具有高折射率的无机纳米微粒引入到传统光学树脂材料,得到了一系列基于不同高折射率纳米微粒的高性能聚合物光学杂化材料,并取得了突破性的进展,所得杂化材料的折射率最高可以达到2.3以上。为了方便广大的科研同行对这类高性能聚合物杂化材料的深入研究以及便于这类材料实现实际的应用价值,笔者基于研究组近十年来的研究成果,从纳米微粒的表面修饰方法和该研究领域的相关应用方面对这类高性能聚合物杂化材料做一个比较系统的介绍。

Optical materials with high refractive index have attracted tremendous attention due to its potential applications in the field of optical, optoelectric,information storage and transfer. However, the traditional optical resin has a small adjustable refractive index,usually below 1.80, which cannot reach the demand of the microminiaturization of the devices in the rapid development society. In the past ten years, our group incorporated high refractive index nanoparticles into polymers and obtained a series of high performance polymer hybrid optical materials based on different high refractive index inorganic nanoparticles, and most of them have a higher refractive index over 1.80. What＇s more, we prepared a super high refractive index than 2.3 based on this strategy. In order to facilitate the fellow for further study of this kind of high performance polymer optical hybrid materials and realize the practical application value of this kind of materials, we summarized the research development from the surface modulation of inorganic nanoparticles to high optical performance for the resulting polymer hybrid optical materials mainly based on our group research achievements.
