Nanocomposites polyaniline/carbon nanofiber

The electrical conductivity, environmental stability, and surface properties of pristine polyanihne can be improved by synthesizing nanocomposite with large surface area materials such as carbon nanofibers [30]. Polyaniline/carbon nanofiber nanocomposite can be prepared by one-step vapor deposition polymerization [31]. In vapor deposition polymerization, a reactor consisting of two connecting flasks are used. In one chamber, the carbon nanofibers soaked in initiator are taken and the other chamber is equipped with a seahng apparatus. Then vacuum is appHed inside the chamber followed by the addition of liquid aniline monomer to the second chamber is carried out. The chamber is heated at low temperature in order to vaporize the anihne monomer. This process can continue... 

Supercapacitors require electrode materials that have good electrical conductivity, good electrochemical properties, high chemical and environmental stabilities, etc. Various ECP/CNM nanocomposites such as polyaniline/carbon nanofiber [31,32,34], polyaniline/graphene [62,67-69], and polypyrrole/graphene [73,75] are widely used as electrode materials in supercapacitors.
