Abstract

Electrostatic force microscopy was used to study the dependence of the electron work function of individual polyaniline/nitrogen doped carbon nanotube (PANI/N-CNT) nanostructures on the duration of synthesis. The work function of nanostructures increases monotonically with the synthesis time increasing. These changes are interpreted as a result of the growth of the polymer layer thickness on CNTs and an increase in the degree of protonation of PANI during the synthesis of PANI/N-CNTs composite.

Highlights

Composite PANI with nitrogen-doped carbon nanotubes (CNTs) (N-CNT) was obtained via in-situ chemical oxidative polymerization of aniline in the presence of nanotubes
Individual nanostructures of PANI/N-CNTs were separate from the volume of the composite by sonication
The suspension was deposited on a Si02/Si substrate for study by AFM
