dc.description.abstractDespite superior properties of carbon nanotubes (CNTs), physical properties of the CNT/epoxy composites are not improved significantly because interfacial bonding between the CNTs and the polymer matrix is weak. CNTs were treated by an acidic solution to
remove impurities and modified subsequently by amine treatment or plasma oxidation to improve interfacial bonding and dispersion
of nanotubes in the epoxy matrix. The functional groups on the surface of treated CNTs were investigated by X-ray photoelectron spectroscopy.
The surface modified CNTs were embedded in the epoxy resin by ultra-sonication and the cured nanotube containing composites
were characterized by field emission scanning electron microscopy. Rheological properties of nanotube containing epoxy resin and
mechanical properties of the modified CNT/epoxy composites were improved because the modification of CNTs improved dispersion
and interaction between the CNT and the epoxy resin.
