Development and characterization of nanoceramic reinforced polyimide-based nanocomposites for high-temperature energy storage applications: a review

Abstract

Recently, PI as high-performance polymer with high glass transition temperature have been regarded as promising matrix for high-temperature dielectric nanocomposites. As such, the review aimed to summarize the influence of nanoceramic fillers on the characteristics of polyimide-based nanocomposites for high-temperature energy storage. Herein, it is worth noting that SiO2, TiO2, AlN, and BN remain favorable reinforcement materials for improving thermal stability, breakdown strength, and energy density of PI-matrix for high-temperature energy storage. Thus, as they depict the potential properties needed in high-temperature dielectrics, the authors concluded the study with challenges/recommendations for further enhancement of PI-based nanocomposites for high-temperature energy storage.
