中文摘要：

半结晶的铁电聚合物在柔性电子器件中极具应用前景，控制晶相生长对其性能优化至关重要。本文通过引入少量（0.2%）单晶单畴的PbTiO3纳米片对P（VDF-TrFE）（简称PVTF）铁电薄膜的生长进行有效调节，获得了高度取向的铁电薄膜且铁电性能得到了大幅提高。PbTiO3纳米片铁电极化对PVTF极性分子的诱导作用可能是薄膜取向生长与性能提高的原因。

英文摘要：

Ferroelectdc polymers are particularly attractive for applications in flexible electronic devices, and controlling its crystalline phase growth is crucial for obtaining optimized ferroelectric properties. Herein we report that a very low introduction （0.2% （w）） of single-domain ferroelectric PbTiO3 nanoplates can effectively mediate the nucleation and subsequent growth of a crystalline phase within P（VDF-TrFE） （denoted by PVTF）, forming highly oriented films and significantly improving the ferroelectric properties due to an alignment of the polarization directions of the polymer and the nanoplates.
