Flexible self-supporting BaTiO3-CoFe2O4 multiferroic self-assembly nanostructure and preparation method thereof
The invention relates to the field of flexible multiferroic magnetoelectric materials, in particular to a flexible self-supporting BaTiO3-CoFe2O4 multiferroic self-assembly nanometer material and a thereof. The flexible self-supporting BaTiO3-CoFe2O4 multiferroic self-assembly nano material comprises a magnetic CoFe2O4 (CFO) daughter and a ferroelectric BaTiO3 (BTO) parent body, the CFO daughter is embedded into the BTO parent body in the form of a nano column to form the 1-3 type composite magnetoelectric multiferroic self-assembly nano material, and the BTO-CFO multiferroic self-assembly nano material is of a flexible self-supporting structure and can be independent from the constraint of a substrate. The flexible self-supporting BaTiO3-CoFe2O4 multiferroic self-assembly nano material disclosed by the invention gets rid of substrate constraint, not only maintains room-temperature ferroelectric and ferromagnetic properties in a self-supporting state, but also has excellent mechanical flexibility, can be spontaneously curled into a tubular shape, and can also be bent and deformed through control.
本申请涉及柔性多铁磁电材料领域，更具体地说，涉及一种柔性自支撑BaTiO3‑CoFe2O4多铁自组装纳米材料及其制备方法。柔性自支撑BaTiO3‑CoFe2O4多铁自组装纳米材料包括磁性CoFe2O4(CFO)子体和铁电性BaTiO3(BTO)母体，CFO子体以纳米柱的形式嵌入BTO母体中构成1‑3型复合磁电多铁自组装纳米材料，BTO‑CFO多铁自组装纳米材料为柔性自支撑结构且可摆脱衬底束缚独立存在。本申请柔性自支撑BaTiO3‑CoFe2O4多铁自组装纳米材料摆脱了衬底束缚，在自支撑状态既保持了室温铁电、铁磁性能，而且具有优异的机械柔性，可以自发卷曲成管状，也可以经过操控进行弯曲变形。
