Abstract Sodium carboxymethyl cellulose (CMC) is used in various applications such as textile, paper, food, pharmaceuticals because of its useful characteristics including non-toxic, non-allergenic, and water-soluble properties. Graphene oxide (GO) and carbon nanotubes (CNTs) can be used as a suitable candidate to improving the mechanical properties of CMC film because of their extraordinary mechanical, electronic, and thermal properties. GO and CNTs can be dispersed in CMC matrix by adequate fabrication methods, resulting in graphene-based nanocomposites with superior mechanical properties. In this work, Sodium carboxymethyl cellulose/graphene oxide/carbon nanotubes (CMC/GCC) nanocomposites were prepared by a simple solution mixing-evaporation method as a function of CNT loading. As GO/CNTs complexes are formed, CNTs can be dispersed in water, indicating that the GO/CNT-filled CMC nanocomposites are prepared environmentally friendly. X-ray diffraction and scanning electron microscopy were used to investigate the structural properties and morphologies, respectively. The mechanical properties of CMC/GCC nanocomposite films were measured by universal testing machine. Compared with pure CMC film and CMC/GO nanocomposite film, it was found that the mechanical properties of CMC/GCC nanocomposite films were enhanced by addition of CNTs.
