摘要
光折变聚合物具有良好的光折变效应,采用以惰性聚合物PMMA为基体,掺杂偶氮化合物染料的光折变聚合物具有较好的光学非线性和稳定性。文章主要介绍使用激光拉曼光谱仪对合成聚合物的各单体和聚合物薄膜进行拉曼光谱扫描,对比分析各个单体成分的特征谱峰与聚合物薄膜特征谱峰,肯定了实验中得到的光折变聚合物薄膜与理论上要求得到的一致性。
Photorefractive polymers have better photo refractive effect, and polymer intermingling Azo compound and PMMA have nonlinear optical （NLO） and stability. The article mainly introduces the Raman spectral scan to several monomer compounding polymer and photorefractive polymer, and contrasts the Raman spectral apex of several monomer and photorefractive polymer. In conclusion we make sure the consistency about the Photorefractive polymers we get through experiment and the ones from theory.
