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，并使全新的器件范例成为可能。本项目旨在开发一种全新形式的多铁性材料，即在纳米尺度上具有电、磁和结构有序参数耦合的自组装有机-无机杂化纳米结构。具体而言，铁磁纳米颗粒将通过共价键合相互作用并入铁电聚合物中以产生巨磁电效应。 本论文将制备铁电聚合物嵌段结构和铁磁纳米粒子，并探索通过超分子自组装来控制纳米粒子的聚集。 这一探索性项目的成功将对设计和合成具有新结构和多功能的活性纳米结构产生深远的影响。能够在传统学科之间的接口工作的未来科学家将在该计划中接受培训和教育。将为中学制作教育录像，并提供辅助教材，对象是7至12年级。

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.
