ABSTRACT

Carbon nanotube (CNT)-reinforced epoxy nanocomposites have attracted significant interest due to their potential in advanced structural and functional applications. In this study, thin-film nanocomposites containing 2 wt% multi-walled carbon nanotubes (MWCNTs) were prepared using a bisphenol-A–based epoxy resin (EDP) and a polyamine hardener. The morphology and chemical structure of the nanocomposites were investigated using Atomic Force Microscopy (AFM) and Fourier-transform infrared spectroscopy (FTIR). AFM images revealed a non-uniform dispersion of CNTs, where both nanoscale networks and agglomerated regions were observed. FTIR spectra indicated partial epoxy ring opening and confirmed the persistence of key functional groups in the cured matrix. The combined results demonstrate that CNT dispersion quality and matrix–filler interactions play a decisive role in defining the structural features of CNT/epoxy nanocomposites. These findings highlight the importance of optimizing preparation and mixing parameters to improve composite uniformity and functional performance.
