    Abstract

    Radio frequency (RF) polymer nanocomposites offer many interesting materials options by combining electric and magnetic materials with structural and processing properties of polymers. For applications in microelectronics and microwave communication systems, ideal material properties would be high permeability and high permittivity, while maintaining low loss. For this study, nanocomposites were cured using diglycidyl ether of bisphenol F (DGEBF) with 4,4′ diamino diphenyl sulfone (DDS) as the curing agent. Nanoparticles used for this study include iron oxide (Fe 3O 4) nanopowder of spherical morphology. To optimize the nanoparticle dispersion within the matrix, an ultrasonication technique was used for synthesis of the composites with varying weight percent of the inclusions. The dielectric properties of the nancomposites were measured using a material/impedance analyzer which measures permeability and permittivity with changing frequency. Initial results show that the iron oxide nancomposites are relatively lossless (properties remain constant with frequency) and have a relative permittivity near 6 and permeability near 2. The composites were found to cure faster with higher loadings of nanopowder, as seen using differential scanning calorimetry (DSC). The cure initiation temperature increased with particle loading, indicating that the very small particles delayed cure. Future research will focus on measuring the mechanical properties of the composites to see if the material can maintain good properties while still having high concentrations of iron oxide filler. Moreover, a more detailed look at the effects on cure characteristics will be carried out. Also, different processing techniques will be used - i.e. microwave processing, compression molding, etc.
