Electrical properties of polyaniline : multi-walled carbon nanotubes nano films

Abstract EN

In this research we study the electrical properties of polyaniline (PANI) nano films pure and doped with multi-walled carbon nanotubes (MWCNTs) and which included direct electrical conductivity (σdc),activation energy and the hall effect with ratio (1%, 3% and 5%) prepared by spin coating deposited on glass substrate at room temperature.

The results showed that (PANI) has conductivity about of (7.136×10-7 (Ω.cm)-1) at room temperature; and this conductivity increased with increasing of doping ratio, also with increasing of temperature as well as the results showed throughout the study that (PANI) has one activation energy and this energy decreased with increasing of doping ratio.

the hall effect showed that the (PANI) its p-type.
