摘要

从直流传导和热脉冲电流(TPC)测量的结果研究了聚醚醚酮(PEEK)的导电机理。在室温下测量了不同电场下PEEK薄膜的直流导电电流。从电场依赖性的结果来看，认为PEEK的传导机制是由跳变引起的。在施加不同电压后的短路条件下得到的TPC谱图表明，在两个电极附近存在异质空间电荷。TPC光谱随外加电场的增大而增大。根据这些结果，我们认为PEEK的导电是由载流子跳变引起的。到达对电极附近的载流子不容易中和，开始形成异电荷

High field properties of polyether-ether-ketone

The mechanism of electrical conduction in PEEK (polyether-ether-ketone) was studied from the results of DC conduction and thermal pulse current (TPC) measurements. The DC conduction current in PEEK films was measured at various electric fields at room temperature. From the results of electric-field dependence, it is thought that the conduction mechanism in PEEK is due to hopping. The TPC spectra, which were obtained under short-circuit conditions after the application of various voltages, show the existence of heterospace charges near the two electrodes. The TPC spectra increase with an increase in the electric field applied. From these results, it is thought that the electrical conduction in PEEK is due to carrier hopping. The carriers reached near the counterelectrode are not easily neutralized and begin to form heterocharges.<>
