Oxidation Resistance of Iron and Copper Foils Coated with Reduced Graphene Oxide Multilayers

Abstract

Protecting the surface of metals such as Fe and Cu from oxidizing is of great importance due to their widespread use. Here, oxidation resistance of Fe and Cu foils was achieved by coating them with reduced graphene oxide (rG-O) sheets. The rG-O-coated Fe and Cu foils were prepared by transferring rG-O multilayers from a SiO(2) substrate onto them. The oxidation resistance of these rG-O-coated metal foils was investigated by Raman spectroscopy, optical microscopy, and scanning electron microscopy after heat treatment at 200 °C in air for 2 h. The bare metal surfaces were severely oxidized, but the rG-O-coated metal surfaces were protected from oxidation. This simple solution process using rG-O is one advantage of the present study.

Surface characterization and corrosion behavior of silanized magnesium coated with graphene for biomedical application

“…Our result indicates that the underlying substrate is protected by a uniform graphene layer. A similar inference has also been made previously on the other metals [23]. The coated GO offered shielding activities on Mg surface, which might offer superior corrosion protection in environment containing chloride ions.…”

Boron Nitride Nanosheets for Metal Protection

“…[2] Recently, graphene, a two-dimensional (2D) nanomaterial, has also been proposed as an oxidation and corrosion barrier on metals. [3][4][5] Graphene has many desirable properties, including a high impermeability to gases (including helium) and moisture, [6] high thermal conductivity [7] and low reactivity to most chemicals. Graphene coatings are also very thin, which minimizes geometric and morphological changes in the protected surface.…”

A corrosion-protective coating based on a solution-processable polymer-grafted graphene oxide nanocomposite

“…Previous work demonstrates that single-layer graphene grown on metal substrates through chemical vapor deposition (CVD) can provide effective short-term corrosion protection for the metal underneath [14][15][16][17][18][19][20][21][22][23][24][25]. However, CVD cannot generate graphene coating on metals that do not catalyze its growth.…”
