However, each method has
its own limitations, such as modification of the protected metal,
thickness of the coating, altering the dimensions and
conductivities of the metal and enormous cost involves in the
coating process. Therefore, the challenge in developing a
protection barrier from corrosion is to develop an economical
yet efficient method for the coating material. In this project, we
developed a cheap and facile method of coating metal surface
with graphene layer for corrosion protection.
