Why is polyimide used in high-temperature energy storage?
Polyimide (PI) is considered one of the most important dielectric materials that can be applied to the high-temperature energy storage field due to its excellent mechanical properties, reasonable dielectric loss, and high breakdown strength.
Why do pi-Paa copolymers have good energy storage properties at high temperatures?
The lower leakage current of the 0.87PI-0.13PAA copolymer led to good energy storage properties at high temperatures. Fig. 13. (a) Schematic of the preparation of PI-PAA copolymer films. The relationship between Ue of PI-PAA copolymers (b) at room temperature and (c) 150 °C . 3.4. The higher-order structures: stacked molecular chains
What is a good energy storage property at 150 °C?
Even at 150 °C, 0.87PI-0.13PAA copolymer still had a high Eb of 517 MV/m and a Ue of 4.6 J/cm 3 (Fig. 13 c), which was highly greater than that of pure PI (3.7 J/cm 3 under Eb of 468 MV/m). The lower leakage current of the 0.87PI-0.13PAA copolymer led to good energy storage properties at high temperatures. Fig. 13.
What is the thermal stability of Pi and TG?
The prepared PI displayed excellent thermal stability even at more than 500 °C, and Tg was at the range of 244–304 °C, maintaining excellent heat resistance. Due to the introduction of the high-polarity sulfonyl group, the sulfonyl group in the molecular structure acted as a permanent dipole, thereby increasing the ϵr (Fig. 5 c).
