The nanomaterial graphene is currently being explored for a number of different applications due to its extraordinary properties and unique 2-D molecular structure. It has recently been proposed as an additive in coatings to provide corrosion resistance. The structure of graphene forms an impermeable barrier that could prevent oxidation of various substrates. Previous attempts have been made to incorporate graphene into polymer coatings; however, some of these coatings have actually caused increased corrosion after extended periods of time. Here, we report a facile wet process to fabricate polyurethane/graphene nanocomposites that could be used in coatings to increase their anticorrosive properties. Various parameters of wet formulations will be discussed and the structure-property correlations will be addressed.
