Novel multi-ferroic nanoparticle-based stretchable composite metamaterials with enhanced magneto dielectric performance
Abstract
The objective of this project is to take advantage in the expertise of USA, Korea and French collaborate to elaborate new composites with advanced applications. The originality relies on the integration of nanomaterials displaying at least two complementary properties: magnetic/electric; electric/mechanical; magnetic/electronic. 1. Nanostructured polymer composites using coated novel magnetic nanomaterials as fillers: nanostructures consisting of oriented aggregates of ferrite nanocrystals with common crystallographic orientation leading to enhanced magnetic collective assembly properties will be doped to enhance magnetic properties for magneto-dielectric properties but also to include multiferroic properties. 2. Film type graphene nanocomposite materials by using novel magnetic nanomaterials as enhanced electromagnetic shielding material. Raspberry shaped magnetic nanomaterials doped with barium and barium ferrite nanocrystals will be assembled with graphene in films and then embedded in a polymer matrix to be tested enhanced electromagnetic shielding material. 3. The test of the novel multi-ferroic nanoparticle based nanocomposite metamaterials for the possibility of real applications. We propose the investigation of highly conductive strain-stable materials made of elastomer fiber mats that can be deposited conformally and patterned directly on 3D substrates. We will use nanoparticle and nanoparticle assemblies dispersed in elastomeric fiber matrices to increase the density of conductive pathways. We plan to investigate the mechanism of the low loss in conductivity subject to large stretching. The characterization of these assemblies as a function of manufacturing conditions will elucidate important correlations between material characteristics and electromechanical properties.
