摘要：

The current to voltage response of a nematic liquid crystal (NLC) sample aligned with a conducting polymer has been measured A deviation from the linear behaviour of the current has been observed for long enough periods of triangular applied voltages. This is connected to the electric charge accumulation at nematic-polymer interface due to the asymmetric carrier injection and to redox phenomena for larger external fields. Our analysis has been carried out in a quasi-static regime in which the nematic director follows the time variation of the applied field without delay.
