In this study, carbon nanotubes were synthesized at temperatures of 500C and 800C by the fluidized-bed chemical vapor deposition method. The synthesized material was purified by using 3 M HCl at 75°C, 15 h. After synthesis and purification, the polyaniline-doped H_3BO_3 and BF_3 and composites were prepared by coagulation method. Transmission electron microscope and Fourier transform infrared spectroscopy were used to characterize the carbon nanotubes and their composites. Thermal stabilities were measured by thermogravimetry and differential scanning calorimetry instruments. The thermogravimetry and derivative thermogravimetry curves indicated that the thermal stability of polyaniline-doped H_3BO_3 and BF_3 increased with carbon nanotube doping. The electrical properties of carbon nanotubes and their composites were also determined. The obtained electrical conductivity values of the nanocomposites including the polyaniline-doped H_3BO_3 and BF_3 were typical for organic semiconductor materials. It can be evaluated that the electrical properties of the polyaniline based polymers can be controlled by carbon nanotube doping.
