The dielectric constant (Dk) and dielectric loss factor (Df) of polyimide under high frequency can be reduced by changing the polarity of polymer and introducing pore structure in summary. In this paper, the research progress of the two modification methods at home and abroad in recent years was summarized. It is indicated that the properties of polyimide can be optimized by adding pore structure on the basis of introducing polar macromolecules. At the same time, the shortcomings of properties characterization in literature were pointed out, and the suggestions were proposed.
