Dielectric properties of three ceramic/epoxy composites
Three ceramic/epoxy composites were under investigation. The ceramic fillers include self-synthesized BaTiO 3 and commercial BaTiO 3 and Pb(Mg 1/3Nb 2/3)O 3. Effects of the filler ratio and testing temperature and frequency on the dielectric properties of these three composites were discussed. The s...

3. Effects of the filler ratio and testing temperature and frequency on the dielectric properties of these three composites were discussed. The self-synthesized BaTiO
3/epoxy composite had the best dielectric property. Its 40%-filler composite had a dielectric constant of 44, which was higher than those of 27 and 24 for the commercial BaTiO

3 composites, respectively. The large ceramic aggregates formed in epoxy are the reason for the self-synthesized BaTiO
3/epoxy composite having a higher dielectric constant of 44. Composite dielectric constant was proportional to the volume ratio of the ceramic filler and remained constant at different test temperatures and frequencies. For the BaTiO
3/epoxy composites, the fabrication process of slurry-casting or screen-printing can have an effect on their porosity. The composites with a low porosity lead to a low dielectric loss tangent. |
