纳米结构铁电图案具有广泛的应用前景，包括传感和驱动、数据存储、光子学、自旋电子学以及能量转换和存储。在这项工作中，一种快速的纳米压印技术的发展，图案铁电聚（偏氟乙烯-三氟乙烯）[P（VDF-TrFE）]共聚物在短短3分钟内，表现出优异的铁电性和压电响应没有任何后压印退火。深入研究了压印条件的影响，并确定了最佳的压印参数，以获得良好的图案转移。本文还讨论了印迹聚合物图形作为铁电非易失性存储器的应用。
Nanostructured ferroelectric patterns are promising for a wide range of applications, including sensing and actuation, data storage, photonics, spintronics, and energy conversion and storage. In this work, a rapid nanoimprinting technique is developed to pattern ferroelectric poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] copolymers in just 3 min, which exhibit excellent ferroelectricity and piezoresponse without any post-imprinting annealing. The effects of imprinting conditions have been thoroughly investigated, and the optimal imprinting parameters for excellent pattern transfer have been identified. The application of the imprinted polymeric patterns as a ferroelectric nonvolatile memory for data storage has also been demonstrated and discussed.
