概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)

To put a few layers of graphene and graphene oxide films on carbon/metal materials with high coverage, the hydrophilization treatment of carbon/metal materials is a key.

実験 / Experimental

In this study, the effect of plasma treatment on the hydrophilization of surfaces of carbon/metal materials is examined. The plasma hydrophilization function of an Au coater was used in this study. TEM samples were prepared by dropping ca. 20 μL of the graphene oxide dispersion onto a holey carbon mesh grid and drying under 120 °C in a vacuum oven. TEM images were observed by a JEOL 2100 TEM with an operating voltage of 200 kV.

結果と考察 / Results and Discussion

By dropping pure water containing graphene oxide flakes on carbon/metal substrates immediately after 25 sec hydrophilization treatment, a few layers graphene oxides could cover on the carbon/metal substrates with high coverage. When quantifoil is used as a grid, the hydrophilic treatment for 180 s can make 1-7 layers of graphene oxide uniformly cover the grid as shown in Fig.1. And the coverage can reach 80%.
