Abstract

Polyetherimide (PEI) is a high-performance thermoplastic engineering plastic. With excellent thermal stability, mechanical strength and chemical stability, it shows wide application potential in many fields. However, its stability at high temperatures and relatively low dielectric constant limit its application. In recent years, researchers have modified PEI by adding conductive fillers, inorganic nano-fillers and developing all-organic composite materials, effectively improving its dielectric properties. However, the balance between the thermal stability and dielectric properties of PEI, as well as the selection and optimization of fillers, remain urgent problems to be solved. In the future, in-depth research can be conducted in the directions of new matrix selection, optimization of filler types and forms, and structural improvement, in order to prepare dielectric materials with high temperature resistance and high energy storage density.
