Blends of dodecylbenzene sulfonic acid-doped polyaniline (PANI-DBSA) with either polyacrylonitrile copolymer (PAN) or polystyrene (PS) were solution cast. The investigation focused on the interaction between the components, the morphology and the resulting electrical conductivity of blends. The results showed that with the same PANI-DBSA content the conductivity of PANI-DBSA/PAN was higher than that of PANI-DBSA/PS. PANI-DBSA was dispersed uniformly in the PAN matrix and its cluster size was rather smaller than in the PS matrix. This is attributed to hydrogen bonding between the carbonyl groups in PAN and the imine groups in PANI, which should lead to better compatibility between PANI-DBSA and PAN.

Secondary dopants and the doping methods were identified for increasing the electrical conductivity of a highly processable and a primarily doped polyaniline dinonylnaphthalene sulfonic acid (PANI-DNNSA). The secondary doping was carried out using film, solution, and vapor doping methods. The doping methods and functional groups of secondary dopants were observed to play a critical role for inducing electrical characteristics of polyaniline. When secondary film doping method and p-toluenesulfonic acid were used, the electrical conductivity of the secondary doped polyaniline was measured to be increased from 0.16 to 334 S/cm. A novel vapor annealing doping method was developed to incorporate secondary dopants into solution cast polyaniline films.

Hydrochloric acid doped polyaniline and camphor sulfonic acid doped polyaniline were prepared by oxidative chemical polymerization and grinding, respectively. The structures of polyaniline samples were measured by Fourier transform infared spectroscopy. The Seebeck coefficient and electrical conductivity of the composites were investigated as protonic acid content in the temperature range from room temperature to 380K. The highest electrical conductivity of the 1M hydrochloric acid doped polyaniline reaches 5.57×102S/m at 320K, and the mass ratio of 1:1 camphor sulfonic acid doped polyaniline reaches 5.97×102S/m at 380K. This work suggests that a new method improves the thermoelectric properties of conducting polymers.

Composites of graphite nanosheets (GNS) fillers in a polyaniline (PANI) matrix doped with dodecylbenzene sulfonic acid were synthesized by polymerization with the aid of sonication. The resulting GNS/PANI composites were characterized by scanning and trans-mission electron microscopy, Fourier transform infrared spectroscopy, X-ray photo-electron spectroscopy, thermogravimetry and electrical conductivity. The results showed that the GNS play an important role in the improvement of thermal stability and electrical conductivity of the composites. Especially, followed the change of GNS contents of the composites, the results of the thermal stability analysis and electrical conductivity analysis got the same variation trend. When the GNS contents for PANI reached 5 wt% in the composites, the best thermal stability and the maximum value of electrical conductivity (6.48 S·cm-1) were obtained.
