Modification of carbon nanotubes and their application in field of electrochemistry

Carbon nanotubes （CNTs） have a great worth of theoretical research and prospective applications in mechanics, electronics and optics due to their excellent mechanical, electrical properties and chemical stability. However, poor dispersibility and low chemical activity of CNTs limit their specific performance, as well as the potential applications in electronic and other fields. This paper mainly describes the covalent and non-covalent modification methods of carbon nanotubes, including the differences and advantages of each method. The main development of carbon nanotuhes as sensors in the field of electrochemistry and environmental analysis are briefly introduced here.
