Original Paper


Eco-friendly polymer composites have drawn much attention over the world because of growing environmental problems. In this study, a new type of nanocomposite film using environmentally friendly cyanoethyl cellulose (CEC) as matrix, reduced graphene oxide (rGO) as conductive filler and montmorillonite (MMT) as disperser of graphene was fabricated by solution blending. The results of SEM, XRD and stationary stand test reveal that MMT increases significantly the dispersibility of rGO. The CEC/rGO/MMT ternary nanocomposite film has a high dielectric constant of 125 and low loss of 0.7 at 1000 Hz when 6.8% rGO and 3.4% MMT were added. Furthermore, the addition of MMT and rGO can notably increase the thermal stability and tensile strength of CEC.
