Abstract

The aim of this research was to align functionalized multiwalled carbon nanotubes (MWCNT)–valine amino acid into a chitosan matrix. At first, the MWCNTs were functionalized with valine amino acid and chitosan/grafted MWCNT-valine composites were prepared via covalently bonding of chitosan on the surface of MWCNT-valine. The functionalized MWCNTs and resulting films were characterized using Fourier transform infrared spectroscopy, thermogravimetric analysis, field-emission scanning electron microscopy, and transmission electron microscopy. A significant synergistic effect of MWCNT provided enhanced mechanical properties and thermal stability on the obtained nanocomposites.
