Nanostructures of polyaniline are great interest since they combine the properties of low-dimensional organic conductors with high surface area materials. In this research, Polyaniline nanorod (PANI-NR) doped with p-touluenesulfonic acid (TSA) was synthesized by template free method. The formation of PANI-NR was confirmed, it was found that their morphology was significantly affected by the concentration of TSA. The variation in the morphology of PANI-NR of grain, rod and grain was observed with increasing concentration of TSA. It is related to the hydrotropic behavior of TSA, and the growth of nanorod is assumed that polyaniline gradually and orderly aggregated in the micelles of sulfonic group for TSA. The conductivity of PANI-NR doped with various concentration of TSA was 10-3 ~ 10-1 S/cm, the diameter and length were 120~180 nm and 0.6 ~ 2 μm, respectively. The morphology, thermal stability and conductivity of synthesized PANI-NR with different doping levels were investigated. |
