Orientation of Carbon Nanotubes Using Electric Field for Applications of Electrochemical Sensors

This paper describes an initial experiment involving the action of an electric field on carbon nanotubes (CNTs). The spatial orientation of nanotubes is assumed due to the influence of electric field. An arrangement of nanotubes could provide better sensor properties of carbon nanotubes. The article describes the realization, course and used parameters of the experiment. The results are presented at the end of the article. The CNT materials used in the initial experiment are multi-walled carbon nanotubes (MWCNT) and MWCNT with the carboxyl group COOH. Selected materials are some of the most used in the field of CNT-based sensor technology.
