文摘

In the present research, excellent dispersion state of graphene in non-polar polymer of polypropylene is achieved via latex technology. A new effective method to reduce graphene oxide (GO) in the polypropylene (PP) latex/GO hybrid film by dipping into reducing agent can prevent the aggregating of graphene nanosheets. The X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) results indicate that the dispersion state of graphene became better as increasing the content of latex. It suggests that the PP latex particles act as separation agent for GO nanosheets. The yield strength of the as-prepared PP/graphene nanocomposites first increases and then decreases with the content of latex increasing; however, the conductivity of the nanocomposites increases significantly with the content of latex increasing. The macroscopic properties are closely related to the dispersion of graphene nanosheets in the as-prepared nanocomposites. Our present research provides a promising approach to fabricate non-polar polymer/graphene nanocomposites with excellent dispersion state of graphene and high performance.
