Effect of Carbon Nanotube Functionalization on the Structure and Electrochemical Characteristics of Their Hybrid Nanocomposites with Polyaniline and Polypyrrole

Hybrid nanocomposites were prepared on the basis of polyaniline (PAn) and polypyrrole (PPy) with functionalized multiwall carbon nanotubes (CNTs). It was shown that the method of functionalization of the CNT and the nature of the polymer have a substantial effect on the structure and electrochemical characteristics of the synthesized nanocomposites. It was established that the conductivity and the capacity characteristics of the PPy/CNT nanocomposites are determined largely by the content of carbon nanotubes, whereas for the PAn/CNT materials they are also determined by the method of functionalization of the CNT. It was shown that the highest capacity (366 and 294 F/g) is characteristic of the nanocomposites based on PAn and CNT (N-CNT) functionalized with the surface catalyst Aliquat 336.
