把非线性光学(NLO)发色基团引入到聚合物主链中,既可以增大聚合物中NLO基团的含量,从而提高聚合物的宏观NLO系数,又能够提高NLO聚合物的极化稳定性。本文报道一种由酚酞环氧树脂(PPh)与对硝基苯胺(NA)得到的NLO聚合物的合成及其极化松弛。 所用酚酞环氧树脂系自制,环氧值0.427。对硝基苯胺北京化工厂产,分析纯。N,N-二甲基甲酰胺为中国医药公司售品,化学纯,用前减压蒸馏精制,乙醇、丙酮均为北京化工厂生产,分析纯。在氮气保护下将等当量的PPh与NA溶于DMF中于150℃反应6～8小时后,倒
The introduction of non-linear optical (NLO) chromophore groups into the polymer backbone can both increase the NLO content in the polymer, thereby increasing the macroscopic NLO coefficient of the polymer and increasing the polarization of the NLO polymer stability. This paper reports the synthesis and polarization relaxation of NLO polymers from phenolphthalein epoxy resin (PPh) and p-nitroaniline (NA). The use of phenolphthalein epoxy system made, epoxy value of 0.427. Nitroaniline Beijing Chemical Plant production, analytical grade. N, N-dimethylformamide for the sale of Chinese medicine companies, chemical pure distillation before use, vacuum distillation, ethanol, acetone are produced in Beijing Chemical Plant, analytical grade. Under the protection of nitrogen, an equivalent amount of PPh and NA were dissolved in DMF and reacted at 150 ° C. for 6 to 8 hours, then poured
