Effect of silane as coupling agent on the dielectric properties of BaTiO3-epoxy composites
The influence of silane coupling agents on the microstructure and dielectric behaviour of epoxy/BaTiO3 composites was studied. Epoxy was diluted using tetrahydrofuran as solvent in order to facilitate the mixing step. Methoxy silane was applied onto ceramic particles. Different diluted aqueous solut...

| Sumario: | The influence of silane coupling agents on the microstructure and dielectric behaviour of epoxy/BaTiO3 composites was studied. Epoxy was diluted using tetrahydrofuran as solvent in order to facilitate the mixing step. Methoxy silane was applied onto ceramic particles. Different diluted aqueous solutions with 0.25, 0.35 and 0.50 wt% of silane/BaTiO3 were used. Dipping technique was utilised to obtain composite films. Dielectric measurements were performed from 25 Hz to 1 MHz and from 20 °C to 120 °C. Composites presented good dielectric properties and a strong dependence with the silane concentration. © 2007 Elsevier Ltd. All rights reserved. |
