    Abstract

    The dc conduction process in polyetheretherketone is discussed from the results of thermally stimulated current (TSC). In TSC spectra, a peak appears at a temperature of about 5-20 °C above the biasing temperature and approaches to the constant temperature of 155 °C when the biasing temperature is higher than 150 °C. This peak shows the maximum value at 155 °C when the biasing temperature is 150 °C. It is considered that this peak is related to the glass transition and caused by the depolarization of an ionic space charge. A drastically increasing current is also observed at temperatures over 180 °C. It is considered that this current is attributed to a spurious current which is spontaneously generated even in a non-biased sample. Both the large current at high temperature and the above mentioned peak in TSC are thought to be related to ionic carriers which may come from byproducts of synthesis. This result is consistent with the dc conduction process, which is mainly due to ionic transport.
