以钛酸钡（BT）为填料，以廉价的热塑性聚氨酯（TPU）为基体，合成了具有陶瓷填料随机分布的高柔性无铅复合薄膜。结果表明，30体积% BT-TPU复合材料具有类似于31的介电常数，这与昂贵且难以生产的PVDF基复合材料相当。在击穿场强为150 kV/mm时，估计能量密度值约为3 J/cm（3）。这些无铅TPU基复合材料为储能应用提供了PVDF基复合材料的替代品。
Highly flexible lead free composite film having random distribution of ceramic filler was synthesized using Barium Titanate (BT) as a filler and inexpensive Thermoplastic Polyurethane (TPU) as a matrix. The results show that the 30 vol% BT-TPU composite has a dielectric constant of similar to 31 which is comparable to the expensive and difficult to produce PVDF based composites. With a breakdown field of 150 kV/mm, an energy density value of similar to 3 J/cm(3) was estimated. These lead-free TPU based composites provide an alternative to PVDF based composites for energy storage applications.
