Electret-based vibration energy harvesting (EH) is advantageous in terms of higher output power at low frequencies and small volumes. We previously found that CYTOP (AGC Chemicals), which is amorphous fluorinated polymer, offers high surface potential. Although the number of repeat units is over 1000, the charging performance is very sensitive to the functional group at both ends.
We recently found through the quantum chemical analysis that the trapped charge is localized at the amide bond, which is formed by the dehydration reaction between the amine added and the carboxyl end group of CYTOP CTX-A.
In this talk, our recent studies on deep-learning-assisted discovery of new CYTOP-based polymer electret are discussed.
