Resumen:
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 20 ºC to 120 ºC. Composites presented good dielectric properties and a strong dependence with the silane concentration.
