摘要：
BiFeO3/PVDF textile composite films with different volume fraction fillers are prepared by electrospinning. PVDF coating effectively prevents the interweaving between fibers, hinders the charge accumulation, prolongs the conductive path, and improves the breakdown field strength of the composite. And the built-in electric field, which is opposite to the external electric field, hinders the effect of the external electric field and improves the breakdown field strength of the composite. The energy storage density of 0.5 vol% BiFeO3/PVDF textile film reaches 9.6 J cm(-3) under the electric field of 380 kV mm(-1).
