摘要

The dependence of polarization fatigue on crystallinity of vinylidene fluoride and trifluoroethylene copolymer films was studied. Experimental data indicated that the higher the crystallinity of the film was

the slower the fatigue rate of the film became. A possible explanation was put forward

and it was regarded that the space charges

trapped at the boundaries of crystallites and/or captured by the defects lying both in amorphous and crystalline phases

should make the major contribution to polarization fatigue.
