Abstract The poly(vinyl chloride) (PVC)/graphene oxide sheets (GO) nanofilms with GO well dispersion were prepared by a solution mixing method. The mechanical and thermal properties of these films were investigated. The results show that the Young’s modulus and the tensile strength of PVC are obviously improved and the high strain at break of PVC is maintained by adding small amount of GO. The tensile strength of PVC has 63% enhancement and the Young’s modulus has 20% enhancement when adding 0.12wt% GO, and the tensile strength increase 125% and the Young’s modulus increase 126% for PVC with 0.6wt% GO. Furthermore, the start decomposition temperature, the maximal decomposition temperature and the char amount of PVC increase in the presence of GO. The higher strength and modulus of GO sheet layer, homodisperse of GO in the PVC matrix, stronger interaction between GO and PVC, layer structure of GO and PVC, result in increase of mechanical propertyies.
