Abstract
Polarization reversal in the ferroelectric polymer PVF2 is known to involve chains rotating in 60° steps. In a 75/25 mol % VF2/VF3 copolymer, chains rotate by two different mechanisms involving either 60° or 180° steps. The extent to which the 180° process contributes to the total polarization reversal is increased by poling.Keywords
