Electrical conduction in acrylic acid doped polystyrene

Abstract

The electrical conductivity of acrylic-acid (AA)-doped polystyrene films (about 100- mu m thick) has been studied as a function of temperature in the range 20-85 degrees C. Power-law dependence of current on voltage has been observed at various temperatures. The value of the power has been found to decrease with increasing temperature and also with increasing dopant concentration. The conductivity was found to increase with an increase in dopant concentration. These effects have been attributed to the formation of charge-transfer complexes (CTCs).<>
