Abstract:

In order to improve the conductivity of the nickel fiber, polyaniline (PANI) of synthesis by chemical oxidative polymerization was coated. The influences of dopant type and content, reaction time, reaction temperature and stirring rate on the conductivity of the PANI coated nickel fiber were investigated. SEM and NMR were used to characterize morphology of products. The conductive of the PANI coated nickel fiber was tested by four-point probe conductivity tester. The results showed that the PANI coated layer was uniform and stabilized when the p-toluene sulfonic acid (PTS) used as dopant, the PANI coated nickel fiber has the highest conductivity of 5×10^-5s∙cm⁻¹when was coated at parameters of the C _(PTS) of 0.1 mol/L, the reaction time of 5 hours, the reaction temperature of 5 °C, as well as the stirring rate of 60 r/min.
