Design and Development of Novel Hierarchically Ordered Block Copolymer-Magnetoelectric Particle Nanocomposites
Abstract
Nanocomposite materials offer a vast design-space of potential material properties, depending on the properties of the constituents and their spatial arrangement. Nanocomposites of polymer/nanoparticle, formed by incorporating nanoparticles into a polymer matrix, have received a great deal of research interest from the scientific community because of the potential performance enhancement relative to either of the non-hybrid constituents. This 36 month effort has led to three major accomplishments: (1) synthesized novel nanostructured composites (i.e., nanocomposites incorporating ferroelectric nanoparticles and SPIONs intimately and permanently capped with polymers on the surface); (2) characterized the nanocomposites developed under 1 by measuring their dielectric and magnetic properties as a function of temperature and frequency; and (3) modeled the dielectric and magnetic properties of the nanocomposites in terms of the electromagnetic parameters and spatial arrangement of the constituents in order to facilitate design of materials with specified properties. The potential benefits of employing ferroelectric and magnetic materials in nanocomposites are manifested not only in the number of applications (e.g., sensors, spintronics devices, capacitors, actuators, transducers, etc.) that are anticipated to fill a critical need in future military, but also in the gaining of fundamental knowledge and expertise on the structure-property relationships in these novel nanostructured materials.
