Mechanism Behind Capacitor’s High-Speed Energy Storage Discovered

6. Wow, they got the science totally wrong in that news article ...

I figured PVDF was poly(vinylidene fluoride), and it is. My next thought was that it would only take a rotational or conformational change for PVDF molecules to reverse polarity completely, and that's what the published abstract indicates.

Replace the word "atomic" with the word "molecular", "charge" with "field", and "state" with "conformation" throughout the 3rd and 4th para in the OP, and it makes physical sense. Otherwise, no.

PVDF, when properly processed, is known to be both ferroelectric and piezoelectric, and (presumably) by raising the glass temperature, can be used to make electrets. Presumably, this is why PVDF was originally investigated for supercapacitors in the first place.
