Are all-organic polymer dielectric films suitable for high-temperature applications?

This work provides a new idea for the design and synthesis of all-organic polymer dielectric films for high temperature applications. The development of polymer dielectrics with both high energy density and low energy loss is a formidable challenge in the area of high-temperature dielectric energy storage.

Can a parylene F film store electrical energy at a high temperature?

These benefits allow Parylene F films to effectively store electrical energy at temperature up to 150 °C, exhibiting a record discharged energy density of 2.92 J cm −3 at charge–discharge efficiency exceeding 90%. This work provides a new idea for the design and synthesis of all-organic polymer dielectric films for high temperature applications.

How does temperature affect the energy storage performance of PP-E films?

The energy storage performance of the films rapidly deteriorates as the temperature rises to 120 °C, as depicted in Fig. 5 b. The PP-E film retains the highest Ue of 3.08 J/cm 3 at 650 kV/mm, representing a 97.4 % increase compared to pristine PP, which exhibits Ue of 1.56 J/cm 3 at 550 kV/mm.

Can grafting a silane coupling agent improve dielectric and energy storage properties?

Three distinct group layers were successfully constructed on the surface of BOPP film, with grafting a silane coupling agent containing an epoxy group identified as the optimal choice for significantly improving both dielectric and energy storage properties.

Are polymer dielectrics suitable for high-temperature energy storage?

The development of polymer dielectrics with both high energy density and low energy loss is a formidable challenge in the area of high-temperature dielectric energy storage. To address this challenge, a class of polymers (Parylene F) are designed by alternating fluorinated aromatic rings and vinyl groups in the pol

What is the EAB of PVA/P (ILS-am) film?

In conclusion, the matching thickness of the films decreases with the increase of the P (ILs-AM) mole 200 fraction, and the EAB is maintained at about 6 GHz. And the EAB of the PVA/P (ILs-AM) film is widest 201 when AM:ILs=10:2 and P (ILs-AM) is 20 mol%, reaching 6 GHz at only 1.9 mm, which exhibits optimal 202 EMA properties.
