Abstract：Graphene oxide nanoribbons(GONRs) were prepared through oxidative longitudinal unzipping of multiwalled carbon nanotubes, and then modified by silane coupling agent, KH-570. The functionalized GONRs(K-GONRs)/EVA composite films were subsequently obtained by solution coating method on a coating machine. Structures and properties of the K-GONRs/EVA composite films were characterized by FTIR, XRD, XPS, TEM, FE-SEM, oxygen transmission rate tester and electronic universal testing machine. The results show that the thin banded K-GONRs with interlayer spacing about 0.970nm are successfully prepared, and there is an increasing in interlayer distance about 0.095nm for K-GONRs when compared with original GONRs. Meanwhile, the prepared K-GONRs is neat and with uniform shape and low defect,dispersed evenly in EVA matrix. Comparing with the pure EVA films, when the mass fraction of K-GONRs is 1%, the oxygen transmission rate of K-GONRs/EVA composite films is reduced by 54.5% and the tensile strength is increased by 89.3%.The barrier property and mechanical properties of EVA is obviously improved.
