摘要

Interfacial interaction and compatibility between the ceramic dielectric and polymer matrix have strong impact on the dielectric constant and dielectric loss of their composites. In this work, the BaTiO3 (BT) nanoparticles were modified by (1) stearic acid (SA); (2) aluminate coupling agent (ACA); (3) the combination of SA and coupling agent aluminate, and then incorporated them with silicone rubber (SR) matrix to prepare BT/SR nanocomposites. The effects of the surface modification methods of BT on the microstructure and electrical properties of BT/SR nanocomposite films were studied. The results showed that SA and ACA were beneficial to the dispersion of BT and resulted in the strong interfacial interaction. The composite of BT modified by SA not only had high dielectric constant of 10.5, 2 times higher than that of the unmodified BT/SR nanocomposite (4.7), at the same time showed lower dielectric loss.
