Carbon nanotube fibers doped with iron via Fenton reaction

Abstract

In a wildly spreading research on carbon nanotube fibers as a potential material for the future, one of the most promising fields are electrical and electronic engineering. As it was mentioned repeatedly the main thing that need to be dealt with for a serious consideration of carbon nanotube structures in application as good conducting wires is a necessity of improvement their electrical conductivity values. In the many possibilities of such electrical properties improve, one of the best is chemical doping. In this work we present a oxidative doping treatment on carbon nanotube fibers via Fenton reaction. However the first assumptions on introduction hydroxide ion doping has changed after performing experiments. The reaction resulted in iron doping on carbon nanotube fibers. Such a result most probably is associated with a great reactivity of carbon nanotube with iron particles. This reactivity is being used in carbon nanotube structures production procedure, due to catalytic action of iron in the issue of carbon nanotube synthesis. This result, however differs from intentions gave us new carbon nanotube-iron composite, which seems to have a great potential for further research.
