Greatly enhanced energy density in poly(vinylidene fluoride-chlorotrifluoroethylene) [P(VDF-CTFE)] is realized through interface effects induced by a photo cross-linking method. Being different from nanocomposites with lowered dielectric strength, the cross-linked P(VDF-CTFE)s possess a high breakdown field as well as remarkably elevated polarization, both of which contribute to the enhanced energy density as high as 22.5 J · cm(-3). Moreover, patterned thin films with various shapes and sizes are fabricated by photolithography, which sheds new light on the integration of PVDF-based electroactive polymers into organic microelectronic devices such as flexible pyroelectric/piezoelectric sensor arrays or non-volatile ferroelectric memory devices.
通过光交联方法诱导的界面效应，聚（偏二氟乙烯-三氟氯乙烯）[P(VDF-CTFE)] 的能量密度得到了极大提高。与介电强度降低的纳米复合材料不同，交联的 P(VDF-CTFE) 具有高击穿场和显著提高的极化率，这两者都有助于将能量密度提高到 22.5 J·cm(-3) 以上。此外，通过光刻技术制备了具有各种形状和尺寸的图案化薄膜，这为将基于 PVDF 的电活性聚合物集成到有机微电子器件中，如柔性热释电/压电传感器阵列或非易失铁电存储器件，提供了新的思路。
