Dielectric properties of plasma-polymerized ferrocene films

The variations of the dielectric constant ε and of tan δ for Al-polyferrocene-Al sandwich structures were studied over the frequency range 40 kHz–50 MHz and the temperature range 30–400°C. Heating in dry air led to a permanent change in the value of ε by approximately 15% while the change in tan δ was of a temporary nature. From IR studies a possible structure for polyferrocene is suggested.
