Notes:
Although many studies have been conducted in the past few years on the possibility ofusing carbon nanotube (CNT) to improve the performance of polymer-based materials, some of theresults were contradictory and lack of coherence. Thus, the in-depth understanding of CNTcomposites is required. In this paper, single-walled carbon nanotubes (SWNTs), which werefunctionalized by sonicating with nitric and sulfuric acids, will be used to fabricate a SWNT/epoxycomposite. There are two reasons for functionalizing the SWNTs, they are (i) to improve thedispersion of the SWNTs in polymer, and (ii) to improve the interfacial bonding properties betweenthe SWNTs and polymer matrix. Tensile property test and micro-hardness test will be carried out toexamine the mechanical properties of the composites with different SWNT contents.Thermogravimetry Analysis (TGA) will be used to evaluate the thermal properties of the composites.Scanning Electron Microscope (SEM) will also be used to investigate the failure mechanism of thecomposites after tensile test. A comparison of the composites with functionalized andnon-functionalized SWNTs will be given to elaborate the effect of nanotube functionalization
