n this paper polyaniline (PANI) has been made through
polymerization of aniline using emulsion polymerization
technique. The polymerization is carried out in an emulsion
comprising water and a non-polar or weakly polar organic
solvent (Xylene) in the presence of the functionalized
protonic acid dodecyl benzene sulphonic acid (DBSA). It is
found that using the emulsion polymerization technique,
conducting PANI-DBSA complexes can be produced that
exhibit high molecular weight, good conductivity and high
solubility in organic solvents in the electrically conducting
state. Electrically conducting polyaniline PANI-DBSA
prepared by an inverted emulsion polymerization in which
DBSA played both roles of surfactant and dopant. Fourier
transform infrared FTIR. spectroscopy for the PANI-DBSA
showed the existence of hydrogen bonding between PANI
and DBSA which indicates the existence of PANI. UVV is
spectra was performed to check the doping level of DBSA.
The electrical conductivity measurement, TGA test and
measurement of viscosity was also studied in the paper.
