- Abstract
- The temperature variation of the thermal conductivity, the electrical resistivity and the thermoelectric power of a graphitized polyimide film has been measured in the temperature range 2 < T < 300 K. The effect of electrochemical intercalation with FeCl4- ions has also been studied. The thermal conductivity results confirm the high degree of graphitization that may be obtained with polyimide films. It shows how intercalation increases the structural disorder and how the intercalate substantially contributes to the thermal conductivity at low temperatures. The electrical-resistivity and thermoelectric-power measurements reveal that the density of free carriers is about three times lower in stage-2 FeCl4- solvated intercalation compounds obtained by an electrochemical way than in stage-2 FeCl3 compounds synthetized by a classical method.
