Data for: Impact of the phenyl thioether contents on the high frequency dielectric loss characteristics of the modified polyimide films

The two files are the datas of the dielectric spectroscopies in the research. The file named permittivity is the database of the relative dielectric permittivities (ε') in the frequency range between 100 Hz to 1 MHz. And the another file named lossfactor is the database of dielectric loss factors (tanδ = ε''/ε').

本数据集包含两份本研究相关的介电谱（dielectric spectroscopy）数据文件。其中名为"permittivity"的文件存储了频率范围为100 Hz至1 MHz的相对介电常数（relative dielectric permittivity，ε'）数据库；另一份名为"lossfactor"的文件则存储了介电损耗因子（dielectric loss factor，tanδ = ε''/ε'）数据库。
