摘要：
The electrical conductivity of polychloroprene (CR)/polyaniline (Pani) blends prepared by bulk and solution processes were investigated. Pani doped with HCl (Pani . HCl) and p-toluenesulfonic acid (Pani . TSA) were employed in vulcanized blends obtained by the bulk process. These blends showed an increase in the conductivity only for blend composition of CR/Pani = 50:50 wt %. At this composition, blends with Pani HCl and Pani . pTSA presented conductivity values of 10(-9) and 10(-10) S . cm(-1) respectively. CR/Pani . HCl blend films prepared by the solution process displayed surface conductivity values of 10(-4) S . cm(-1) with as low as 10-15 wt % of PAni . HCl. Surface analysis of these blends by X-ray photoelectron spectroscopy indicated no traces of the conductive additive. The surface composition was found to be exclusively constituted of CR.
