Nanostructured Electrode of Multi-Walled Carbon Nanotubes and Polyaniline Nanofibers

Polyaniline (PANi), an electroactive polymer, is known for its high electrical conductivity, 
excellent thermal  stability and interesting redox behavior. On the other hand, multi-walled carbon nanotubes (MWNT) are known for their high aspect ratio, rich functionalization chemistry and high conductivity. Nanostructured films of PANi and MWNTs could serve as potential electrode materials for supercapacitors, batteries, sensors, and photovoltaic devices.

We are investigating the physicochemical and electrical properties of ultrathin electrodes 
of polyaniline nanofibers and acid functionalized multiwalled nanotubes fabricated using layer-by-
layer (LbL) assembly.The resulting elecreodes consist of a randomly oriented nanoscale 
interpenetrating network structure with well developed nanopores indicates that yield excellent 
electrochemical performance that could potentially be applied in supercapacitors, fuel cells, and 
battery electrodes.
