Collaborative Research and Development Delivery Order 0024: Synthesis, Processing, and Evaluation of Polymers for RF Applications
Abstract
This research in support of the Air Force Research Laboratory Materials and Manufacturing Directorate was conducted at the Air Force Research Laboratory (AFRL) from 1 June 2004 through 31 December 2005. RF polymer nanocomposites containing ferrite nanoparticle and core/shell nanoparticles dispersed in polyurethane have been prepared. the permittivity in the X-band was found to increase with increasing nanoparticle volume inclusion and with increasing nanoparticle size. In the CoFeO4/FeO4 core/shell nanoparticle nanocomposite, the addition of the Fe3O4 shell lowered the permittivity compared to the native CoFeO4 particle and increasing the shell thickness further depressed the permittivity. In the FeO4/CoFe2O4 core/shell, the permittivity increase with the addition of the shell.
