Rational design of all-organic flexible high-temperature polymer dielectrics

Advanced polymer dielectrics are desired for high-temperature, high-density, and high-efficiency energy storage. The paradox of mutually exclusive constraints between high field endurance, dielec-tric polarization, and thermal stability amounts to a huge obstacle in the design of all-organic polymer dielectrics for safe operation un-der harsh conditions. Although there are a plethora of functional group class polymers that have been investigated and reported, there remains a large unexplored design space. A perspective of the magnitude of the grand challenge, accelerated and targeted exploration of polymer dielectrics with the rational molecular design assisted by informatics-based approaches, is presented here for the generative design and further development of poly-mers with superior thermal stability, high electric field endurance, and strong dielectric polarization.

Automated summary

Advanced polymer dielectrics are essential for high-temperature, high-density, and high-efficiency energy storage. The design of all-organic polymer dielectrics faces challenges due to mutually exclusive constraints between high field endurance, dielectric polarization, and thermal stability, which requires accelerated and targeted exploration with rational molecular design assisted by informatics-based approaches.
