In the present work, carbon nanotube-reinforced carboxymethyl cellulose (CMC/CNT) nanocomposites were prepared by a solution casting method. The CNTs can be homogeneously dispersed in water with the aid of CMC polymer and was used as reinforcement. The crystal structure and morphologies of pure CMC, CNTs, and CMC/CNT nanocomposites were investigated by X-ray diffraction, transmission electron microscopy, and scanning electron microscope, respectively. The mechanical behaviors, tensile strength and Young’s modulus, of the CMC/CNT nanocomposite films were estimated by universal testing machine after cutting films to specimens using ASTM D638-05 blade. As a result, the tensile strength and Young’s modulus of CMC/CNT nanocomposites were enhanced by addition of the CNT owing to π–π interfacial interaction between CNT and CMC polymer chain. |
