“…For RuO 2 , the characteristic peaks (36.2 , 53.2 , and 64.1 ) displayed the low crystalline state of the sample and the existence of amorphous. [16][17][18][19] The patterns of PANI/RuO 2 composites are similar to those of the pristine PANI. Two broad peak at 2 = 25 2 and 36.2 indicate the presence of PANI and RuO 2 .…”

Polyaniline (PANI)/ruthenium oxide (RuO2) composites were prepared by a chemical oxidation polymerization with various amount of hydrous RuO2. In the PANI/RuO2 composites, RuO2 particles were surrounded by PANI. The morphology and structure of the PANI/RuO2 composites were examined by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). Analysis by TEM revealed that the aggregations of the composites were increased with the amounts of hydrous RuO2. Electrochemical performances of prepared composites were characterized by cyclic voltammetry (CV). The composites prepared with 20 wt% of hydrous RuO2 per aniline monomer showed the highest specific capacitance of 710 F/g at 5 mV/s among the prepared composites. However, the specific capacitance of the composites with excess amounts of hydrous RuO2 is lower than the highest one. The large aggregation of RuO2 particles prevents the participation in electrochemical reaction due to the long pathway from the electrolyte and a decrease of effective surface area.

“…As a typical electrode material of pseudocapacitors, polyaniline (PANI) has attracted wide interests because of its excellent capacity for energy storage, easy synthesis in aqueous medium, high conductivity, good environmental stability in air, simplicity in doping, low price of aniline monomer, and ease of manipulation . All of these have made it to be an exceptionally versatile material with application in energy storage/conversion devices.…”

Polyaniline=tailored carbon nanotubes composite (PANI=TCN) synthesized via situ polymerization of aniline monomer in the presence of tailored carbon nanotubes (TCN) is reported as electrode material for supercapacitors. The morphology, structure, and thermostability of the composite were characterized by scanning electron microscope, Fourier transform infrared, and thermogravimetric analysis. The electrochemical property of the resulting material was systematically studied using cyclic voltammetry and galvanostatic charge-discharge. The results show that the short rod-like PANI dispersed well in the TCN with three-dimensional network structure. The as-prepared composite shows high specific capacitance and good cycling stability. A specific capacitance of 373.5 F g 21 at a current density of 0.5 A g 21 was achieved, which is much higher than that of pure PANI (324 F g 21 ). Meanwhile, the composite retains 61.7% capacity after 1000 cycles at a scan rate of 50 mV s 21 . The enhanced specific capacitance and capacity retention indicates the potential of composite as a promising supercapacitor electrode material. V C 2013 Wiley Periodicals, Inc. J. Appl. Polym.
