摘要

Coated nanoparticles are used to produce ceramic-polymer na-nocomposites with interesting physical properties. The ceramic cores of the particles are produced in a microwave plasma. The monomers of interest are evaporated and inserted directly after the plasma reaction zone. Acrylic-based monomers, fluorinated monomers and C_(20)F_(42) are used for the polymer coating. The ceramic-polymer nanocomposites generally contain 50 to 70 Vol-% of polymer. The complex high frequency permittivity, ε_r = ε′ - jε″, is determined with a vector network analyser in the frequency range from 10 MHz to 8 GHz. The ceramic/polymer nanocomposite shows an increased permittivity compared to that of the pure polymer. Slight frequency dependency is observed. The permittivity can be adjusted by the ceramic/polymer ratios.
