Functionalization of Carbon Nanotube Surface via UV/O3 Treatment

Article Preview

Abstract:

The carbon nanotube (CNT) surface is successfully modified using the UV/Ozone treatment and a triethylenetetramine (TETA) solution for use as the reinforcement for polymer matrix nanocomposites. These treatments along with ultrasonication are aimed to disperse the CNTs uniformly in the resin matrix, as well as to provide the CNT surface with chemical functionalities for adhesion with resin. Fourier transform infra-red (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) are performed to evaluate the changes in chemical structure and surface functional groups arising from the chemical treatment. The practical implications of the surface functional groups for improving the interfacial adhesion are discussed.
