FIG. 1.

Isotherms of the imaginary part of the permittivity vs frequency at room temperature (292 K) for conducting PAni and zeolite-PAni blends (curves from top to bottom correspond to PAni, 10, 25, 35, and zeolite-PAni blends). Inset: Room temperature frequency-independent conductivity vs the content in zeolite.

Image of FIG. 2.
FIG. 2.

Temperature dependence of the measured (first column) and obtained after subtraction of the dc component from the measured (last column) vs frequency. In each plot, curves from top to bottom correspond to 292, 248, 175, 135, 107, and 87 K.
