Abstract

Nano-scaled P2ClAn was synthesized via chemical oxidation polymerization. The effects of oxidant concentration, surfactant type and concentration on the synthesized P2ClAn were investigated. Electrical conductivity results revealed that the undoped P2ClAn synthesized by APS at the monomer:oxidant mole ratio of 1:1 was the most suitable condition to yield the highest P2ClAn electrical conductivity. The morphological structures of P2ClAn changed from an irregular-shaped structure to a cylinder shape or a flake-like shape depending on the surfactant type and concentration. P2ClAn in the presence of SDS, used as a surfactant template, provided particles with an average nanosize of 56.2 nm and higher electrical conductivity than using CTAB. Further doping process of P2ClAn was studied using HClO4. The electrical conductivity of the doped dP2ClAn/SDS50 increased by three orders of magnitude, at the monomer:doping mole ratio of 1:25 possessing the highest electrical conductivity of 10.47 S cm−1, relative to the synthesized P2ClAn without doping.
