Poly(lactic acid) (PLA)/graphene oxide (GO) nanocomposites containing 0.5 wt% to 2 wt% GO were prepared via solution mixing and the crystallinity, rheological and electrical properties of them were studied. It was found that the incorporation of GO leads to improve the storage modulus, loss modulus, and complex viscosity of the nanocomposite samples significantly. Also differential scanning calorimetry (DSC) results indicated that GO is an effective nucleating agent for PLA and could increase its crystallinity and decrease the crystallinity temperature. Also it was resulted that by introducing the GO in PLA matrix, the electrical resistance of samples are decreased, especially at low frequencies.
