Effect of surfactant on conductivity of Poly(pyrrole-co-formyl pyrrole) via Emulsion Polymerization

Poly(pyrrole-co-formyl pyrrole), P(Py-co-FPy), were synthesized via emulsion polymerization using sodium dodecylsulfate (SDS) and poly(styrenesulfonate) (PSS) as surfactants and trifluoroacetic acid (TFA) as a catalyst. Amounts of surfactant were vary as mole ratio of surfactant: monomer (0.25, 0.5 and 1.0). The synthesis copolymers were characterized by FTIR, SEM, particle size analyzer and four point probes. As a result of FT-IR spectra proved that the synthesized copolymers are associated with the structure of the P(Py-co-FPy). Spherical particles were detected by SEM and particles diameter is in range of 60-600 nm depending on type and amounts of surfactant. The electrical conductivity is in the range of 1.74x 10(-5) to 2.21 x 10(-3) S/cm. The P(Py-co-FPy) nanoparticles doped with PSS are higher conductivity than doped with PSS.
