Direct grafting of carbon nanotubes with ethylenediamine
MetadataShow full item record
Singlewall and multiwall carbon nanotubes were covalently functionalised with ethylenediamine(EDA) in a simple one-pot process providing a good surface coverage. The successful grafting of EDAon carbon nanotubes (CNTs) was shown by X-ray photoelectron spectroscopy (XPS), infrared andRaman spectroscopies and thermogravimetric analysis (TGA). These functionalised CNTs withterminal amino groups were shown to form composite polyamide materials with uniform CNTdistribution in the polymer matrix.
