| 摘 要： | 用Ｖ－棱镜折射率仪通过对３－（１，１－二氰基噻吩）－１－苯－４，５－二羟基Ｈ－噻唑（ＤＣＮＰ）与聚醚醚酮（ＰＥＫ－ｃ）组成的主客掺杂聚合物溶液的折射率的测量，在利用了Ｌｏｒｅｎｚ－Ｌｏｒｅｎｔｚ局域场的情况下，计算出了聚合物体系的折射率。由Ｓｅｌｌｍｅｙｅｒ色散方程对所测聚合物体系折射率的模拟，得到了聚合物体系折射率的色散曲线。聚合物的折射率的测量精度约为０．７％，而且聚合物与溶剂的折射率大的差值

| Abstract: | The refractive indices of a guest-host polymer system made up of DCNP and polyetherketone(PEK- c)were measured with the polymer solutions by using V-prism refractometer.The Lorenz-Lorentz local field formalism was used for the calculation of the refractive indices of the polymers from the measured indices of the polymer solutions and the pure solvent. The refractive index dispersions of the polymers were obtained by fitting the measured indices of the polymers to Sellmeyer equation. The method allows for an accuracy in Index of 0.7%.In addition, a large difference between the indices of the polymer and the solvent and a solution with a higher polymer volume fraction are favorable for a high accuracy. |
