As graphene oxide/CNT complexes (GCC) are formed by π-π interactions, CNTs can be dispersed in water, indicating that the GCC-filled CMC nanocomposites are prepared environmentally friendly. Therefore, GCC-reinforced sodium carboxymethyl cellulose (CMC/GCC) nanocomposites were fabricated by a simple solution mixing-evaporation method as a function of CNTs amount. X-ray diffraction and scanning electron microscopy were performed to investigate the crystal structures and morphologies, respectively. The mechanical properties of CMC/GCC nanocomposite films were evaluated by universal testing machine after cutting films to specimens using ASTM D638-05 blade. Compared with pure CMC film and CMC/GO nanocomposite film, it was found that the mechanical properties of CMC/GCC nanocomposite films were enhanced with adding the CNTs. |
