Efficient coating of polystyrene microspheres with graphene nanosheets.

چکیده
Herein, we propose a facile and efficient method to obtain the polystyrene/graphene nanosheets (PS/GNSs) nanocomposite particles. As far as we know, it is the first example that GNSs are attached onto the surface of PS microspheres, with such smooth morphology, and without relying on any surface pretreatments of substrate microspheres.

Performance comparison of graphene and graphene oxide-supported palladium nanoparticles as a highly efficient catalyst in oxygen reduction
In this work, the performance of graphene nanosheets (GNs) and graphene oxide (GO) nanosheets, as a support for palladium nanoparticles (PdNPs) toward oxygen reduction reaction (ORR), was studied. The graphene nanosheets were functionalized by a new and simple method. The PdNPs were synthesized on a glassy carbon electrode (GCE) modified with GNs or GO via a potentiostatic method; without using...
متن کاملMechanical and Anticorrosive Properties of Graphene/Epoxy Resin Composites Coating Prepared by in-Situ Method
The graphene nanosheets-based epoxy resin coating (0, 0.1, 0.4 and 0.7 wt %) was prepared by a situ-synthesis method. The effect of polyvinylpyrrolidone/reduced graphene oxide (PVP-rGO) on mechanical and thermal properties of epoxy resin coating was investigated using nanoindentation technique and thermogravimetric analysis, respectively. A significant enhancement (ca. 213% and 73 °C) in the Yo...
