摘要

针对聚醚酰亚胺（PEI）在高温（

100 ℃）、强电场（

400 MV/m）下因电导损耗增大导致介电储能性能大幅度下降的难题，提出基于高电子亲和能单体的共聚改性方法来提升材料高温储能性能。采用1，4，5，8-萘四甲酸二酐（NTCDA）单体与常规的PEI单体进行共聚反应制备系列NTCDA-PEI（nPEI）薄膜，研究了不同NTCDA共聚比例对材料热性能、介电性能、击穿性能和储能性能的影响规律，并结合跳跃电导模型和热刺激电流测量，分析了共聚薄膜的电导和陷阱特性对储能性能影响的内在机制。结果表明：共聚薄膜在介质中引入了更多的电子陷阱，有效抑制了高温下载流子的迁移，实现了电导电流的下降和击穿电场强度击穿场强的提高，进而使nPEI薄膜在高温下实现放电能量密度与充放电效率的提升。当NTCDA物质的量分数为1.5%时，共聚薄膜性能如下：在150 ℃下的性能最优，击穿电场强度为574.35 MV/m，比纯PEI提高了14

.0%；最大放电能量密度为6.38 J/cm

，比纯PEI提高了50.8%；充放电效率从纯PEI的52.2%提升至88.7%。该研究为开发适用于高温环境下的储能器件提供了一种解决方案。

Abstract

In order to tackle the issue of a significant decrease in dielectric energy storage performance of poly (etherimide) (PEI) at high temperature (

100 ℃) and in high electric field (

400 MV/m) due to the increase of conductivity loss

a copolymerization modification method based on high electron affinity monomer was proposed to improve the high temperature energy storage performance of PEI. A series of NTCDA-PEI (nPEI) films were prepared by copolymerization of 1

8-naphthalenetetracarboxylic dianhydride (NTCDA) monomers and conventional PEI monomers. The effects of different NTCDA copolymerization ratios on thermal properties

dielectric properties

breakdown properties and energy storage properties of the materials were studied. In addition

by leveraging the hopping conductance model and the thermal stimulation current measurement

the internal mechanism of the influence of the conductance and trap characteristics on the energy storage performance of the copolymer films was analyzed. The results showed that the copolymerized films introduced more electron traps

effectively suppressed the carrier migration at high temperature

realized the decrease of conductive current and the increase of breakdown electric field strength

and then improved the discharge energy density and charge and discharge efficiency of nPEI films at high temperature. When the NTCDA's molar content was 1.5%

the performance of the copolymerized film was the best at 150 ℃

and the breakdown strength was 574.35 MV/m

which is 14.0% higher than that of pure PEI. The maximum discharge energy density was 6.38 J/cm

which is 50.8% higher than that of pure PEI. The charge and discharge efficiency increased from 52.2% of pure PEI to 88.7%. This study provides a solution for the development of energy storage devices su

itable for high temperature environments.
