Block Copolymer Magnetic Nanoarchitectures for RF Applications

Abstract

The goal of this research is to develop novel polymer nanocomposites with improved shape-flexibility, ease in processing, and high ratio of magnetic permeability ((mu)r) to dielectric permittivity ((epsilon)r) for smaller physical size, wider bandwidth, and higher power efficiency antenna systems. The research effort consisted of: 1) investigation of the influence of nanoparticle dimension, chemical composition, and orientation within polymer matrices on magneto-dielectric properties, 2) synthesis of polymer compatible, low energy loss nickel zinc iron oxide magnetic nanoparticlcs with various particle sizes, 3) polymer antenna construction and evaluation of performance.
