Preparation for ferroelectric-ferromagnetic composite nano-fiber

一种制备铁电铁磁复合纳米纤维的方法

Abstract

The invention provides a method that can successively produce ferroelectric and ferromagnetic composite nano fiber, is simple, convenient and low in cost and comprises the following processing steps: (1) ferroelectric precursor solution is prepared; (2) ferromagnetic precursor solution is prepared; (3) ferroelectric and ferromagnetic composite solution is prepared; (4) electrostatic spinning is adopted to prepare the ferroelectric and ferromagnetic composite nano fiber; (5) roasting is carried out to obtain the ferroelectric and ferromagnetic composite nano fiber with stable performances. The ferroelectric and ferromagnetic composite nano fiber provided by the invention can ensure uniform composition of ferroelectric phase and ferromagnetic phase in the molecular scale and even in the atomic scale and greatly increase contact area, thus resulting in higher magneto-electric coupling coefficient; the technique of the invention has broad application prospects in fields such as a convertor, an attenuator, a filter, a probe, a spin valve and a biconditional storage unit, etc.
本发明提供了一种简单、方便、成本低廉、可连续生产铁电铁磁复合纳米纤维的方法,包括以下工艺步骤:①铁电前驱体溶液的配制;②铁磁前驱体溶液的配制;③铁电铁磁复合溶液的配制;④静电纺丝制备铁电铁磁复合纳米纤维;⑤煅烧获得性能稳定的铁电铁磁复合纳米纤维。本发明制备的铁电铁磁复合纳米纤维可以使铁电相和铁磁相在分子乃至原子尺度上均匀复合,接触面积大大增加,从而使磁电耦合系数更高。本发明技术在转换器、衰减器、过滤器、场探针、自旋阀及双态存贮器等领域拥有广阔的应用前景。
