摘要：

BaTiO3-polymer composite layers have been produced by the spin-on technique (thickness 3-10 mum). The dielectric permittivity of the layers at room temperature can be tuned from 2.8 to approximately 33 by varying the ceramic filling from 0 to 60% by volume. The dielectric properties of the films are almost insensitive to temperature variations in the range 20-180 degreesC. Free-standing composite layers with ceramic content less than or equal to 50% are flexible without noticeable change of permittivity after repeated mechanical bending.
