Blends based on quaternized polysulfones were investigated in terms of optical and electronic properties. By applying the Bicerano formalism the refractive index and dielectric constant were evaluated. Also, the dielectric constant of these blends was studied as a function of temperature and frequency. As the result of the main chain structure and charged groups, an increase in theoretical values of the refractive index and dielectric constant with increasing of the ionic quaternized units content in the polymer blend occurs. Additionally, decrease in the dielectric constant with the increase of frequency and decrease of temperature was observed. Refractive index and dielectric constant values indicate that the analyzed samples are transparent and can be used in obtaining of materials with applications involving a small polarizability. Thus, the results are important in prediction of the special optoelectronic features of new polymers blends to obtain high-performance materials with applications in electronic and biomedical fields.

基于季铵化聚砜的共混物某些光电性能的预测方法

研究了基于季铵化聚砜的共混物的光学和电子性能。通过采用Bicerano形式主义，可以评估折射率和介电常数。此外，还研究了这些共混物的介电常数与温度和频率的关系。作为主链结构和带电基团的结果，随着聚合物共混物中离子季铵化单元含量的增加，发生了折射率和介电常数的理论值的增加。另外，观察到介电常数随频率的增加和温度的降低而降低。折射率和介电常数值表明所分析的样品是透明的，可用于获得极化率较小的材料。因此，
