The contact electrification of ferroelectric polymer can be more complicated due to its ordered permanent molecular dipoles and dipole–dipole interactions. Herein, the  polyvinylidene fluoride (PVDF)‐Cu is taken as an example to investigate the mechanism of ferroelectric polymer‐metal contact electr...
