Improved electro-mechanical properties of carbon nanotubes network embedded in elastic polyurethane by oxidation

摘要

The functionalization of multi-walled carbon nanotubes using KMnO_4 oxidation has affect on the electrical resistance of nanotube network/polyurethane composite subjected to elongation. The effect was tested in the course of elongating/relaxing cycles. The results show a multiple increase of electromechanical properties of the composite with KMnO_4 oxidized nanotubes than the composite with pristine nanotubes.
