NER: Organic-Inorganic Multifunctional Nano-hybrids Exhibiting Multiferroics

多铁性材料中铁电性和铁磁性的共存开辟了许多新的交叉耦合现象，并实现了全新的器件范式。本项目旨在开发具有耦合电、磁和结构有序参数的自组装有机-无机杂化纳米结构，作为一种全新形式的多铁性材料。具体来说，铁磁性纳米颗粒将通过共价键相互作用结合到铁电聚合物中，从而产生巨大的磁电效应。制备了铁电聚合物和铁磁纳米颗粒的块结构，并探索了通过超分子自组装控制纳米颗粒聚集的方法。这一探索项目的成功将对具有新结构和多种功能的活性纳米结构的设计和合成产生深远的影响。能够在传统学科之间工作的未来科学家将在该计划中接受培训和教育。将为中学7年级至12年级制作教育视频和配套的课堂材料。

The co-existence of ferroelectricity and ferromagnetism in multiferroic materials opens up a host of new cross-coupled phenomena and enables entirely new device paradigms. This project seeks to develop self-assembled organic-inorganic hybrid nanostructures with coupled electric, magnetic, and structural order parameters at nanometer scale as a totally new form of multiferroic materials. Specifically, the ferromagnetic nanoparticles will be incorporated into the ferroelectric polymers via covalent bonding interactions for colossal magneto-electric effect. The block structures of ferroelectric polymers and ferromagnetic nanoparticles will be prepared and explored to the control of the nanoparticle aggregation via supramolecular self-assembly. The success of this exploratory project will have profound implications for design and synthesis of active nanostructures with new architectures and multiple functionalities. Future scientists capable of working at the interface between traditional disciplines will be trained and educated within this program. Educational videos with supporting classroom materials will be produced for secondary schools, targeting the 7th through 12th grades.
