Enhanced Electromechanical Properties of Carbon Nanotube/Polyurethan Composite by KMnO₄ Oxidation

Abstract:

The effect of oxidation of multi-walled carbon nanotubes by KMnO₄ on the electrical resistance of a nanotube network/polyurethane composite subjected to bending has been studied. In this respect, the main achievement is a multiple increase of gauge factor for the evaluating electromechanical properties of the composite after nanotube oxidation with KMnO₄. It indicates favorable properties of the composite for its use as a high-deformation strain-sensing element.
