Uncapping Multi-Walled Carbon Nanotubes Using Wet Chemical and Oxidation Methods

摘要

Different materials can be introduced into hollow space of carbon nanotubes and result in very useful udnanostructures for different applications such as energy storage, self-healing materials, nanocomposites, udetc. In this study, the multi-walled carbon nanotubes were uncapped using two methods, oxidation with udcarbon dioxide or oxygen at elevated temperatures, and boiling carbon nanotubes in concentrated nitric acid chemical method was found to be more effective than the oxidation method, since the number of opened nanotubes was about 60 % more than that in oxidation method. Furthermore, unlike the oxidation method, no udweight loss was observed in the chemical method.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35060
