摘要
本文从降低聚酰亚胺在高频下的介电常数(D_(k))和介质损耗因数(D_(f))出发,将其改性方法归纳为改变聚合物极性和引入孔隙结构两方面,综述了近几年国内外相关的研究进展,发现在引入极性大分子的同时添加孔隙结构,可使得聚酰亚胺的介电性能达到最优,同时指出了文献中性能表征的不足并提出了建议。
The dielectric constant(D_(k))and dielectric loss factor(D_(f))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.
