Functional or smart coatings (organic, inorganic, or hybrid) are materials that can be adapted for many applications where they must be able to perform a well-defined set of functions such as improved theirs chemical, mechanical, electrical and magnetic properties. One of the objectives of this project was to study the efficiency of nanoaditivated graphene in an anticorrosive epoxy coating. The composites were synthesized by the addition of graphene in a polymeric matrix in the contents of 0.1 and 0.5 percent (w/w). For the graphene characterization, XRD diffractograms and AFM images were obtained. Characterization techniques such as Fourier Transform Infrared Spectroscopy (FTIR) and Raman were applied to obtain relevant information on the molecular structure and interaction between epoxy resin and graphene molecules. Thermal Analysis was performed to analyze the material thermal resistance and to determine the glass transition temperature of cured nanocomposite. The thermogravimetry results did not indicate a significant change in the glass transition temperature of the polymeric matrix when submitted to the addition of the nanocharge. This may be related to an incomplete curing process of the resin and/or the presence of defects in the graphene sample. Atlas cell immersion tests and cyclic tests results indicate that graphene additions promote improvements to the epoxy coating concerning corrosion resistance, especially at the concentration of 0.1 percent by weight. Because of the significant demand of industry for steel corrosion protection, the understanding of interaction between epoxy coating and graphene as a filler is very relevant in direction to find out superior anticorrosive properties.
