Study of Impact on Carbon Nanotubes by Electrochemical Treatment

Abstract

The temperature conditions of electroconductivity of beginning and electrochemically hydrogenated tapered CNTs were researched by utilizing four-test van der Pauw strategy. The investigations uncovered that the electrochemical hydrogen ingestion leaded to a critical decrease in the electroconductivity of cone shaped carbon nanotubes. We expect that these progressions can be related with a reduction in the centralization of charge bearers because of hydrogen limitation on the carbon π-orbitals, the change from sp2 to sp3 hybridization of cone shaped CNTs band structure, and, in this way, a metal-semiconductor-cover progress.
