Effect of 1-chloro-2,3-epoxy-propane on the conduction mechanism in polyvinyl chloride
摘要
The nature of the electrical conduction in polyvinyl chloride (PVC) containing 1-chloro-2,3-epoxy-propane has been studied at a constant temperature of 297 K. In the first region of the I-V characteristics (slope 
1), the conduction is Ohmic because there is no injection of carriers from the electrode contact. The Richardson-Schottky effect is the predominant conduction mechanism in the second region (slope 2). The variation of dc conductivity, σ, may be due to the combined effect of change in σ with temperature, and the nature of trap distribution in the sample. At higher temperatures, the increase in σ may be due to the sample softening.
