重构蓝宝石表面诱导PVDF-TrFE纳米结构及其性质研究
Study on the Properties of PVDF-TrFE Nanostructures Induced by Reconstruction of Sapphire Surface
摘要: 本文利用m面蓝宝石表面重构形成的纳米沟槽，诱导生长一维纳米棒和二维纳米薄膜的PVDF-TrFE，研究了其表面形貌特征，压电和铁电性质。结果显示纳米棒的长宽比可以达到50，通过施加不同正负电压，观察到单畴结构的翻转。并且相位与振幅滞回线分析证明相位翻转为180˚、d*33约8 pm/V。所得结果表明在纳米结构中PVDF-TrFE依然保持着较好的压电和铁电性质。
Abstract: One-dimensional nanorods and two-dimensional nanofilms of PVDF-TrFE were prepared on reconstructed m-plane sapphire surface. The surface morphology, as well as piezo/ferroelectric properties of PVDF-TrFE, was studied. The results show that the aspect ratio of the nanorods can reach 50. By applying different voltages, the ferroelectric switching is observed in the single domain structure. In addition, the analysis of phase hysteresis loops and amplitude proves that the phase switching can reach 180˚ and the d*33 is about 8 pm/V. These results indicate that nanostructured PVDF-TrFE exhibits reasonable piezoelectric and ferroelectric properties.
