Study on the Effect of Graphene on Characteristics of Inorganic Polymer Paint

This study investigates the effects of graphene on the thermal resistance, corrosion resistance, and surface morphology of inorganic polymer paints. Graphene was incorporated into the paint at concentrations of 0.01, 0.02, 0.05, 0.1, and 0.2% by weight, and its influence was analyzed using a variety of methods, including TGA/DTA thermal analysis, SEM/FESEM imaging, electrochemical impedance spectroscopy (EIS), polarization curve measurements, and FTIR spectroscopy. The findings revealed that the addition of graphene significantly improved the overall performance of the paint. Notably, the optimal graphene concentration of 0.05% increased the heat resistance to 798 °C (5% improvement over the control) and enhanced corrosion resistance by approximately 20% compared to samples without graphene. Furthermore, the graphene-enhanced paint demonstrated smoother surface morphology and improved coating adhesion, with a noticeable reduction in particle porosity and better uniformity, as observed in SEM images. The results also indicate that excessive graphene content (>0.05%) negatively impacts performance due to poor dispersion and surface defects. Importantly, the study confirms the successful integration of graphene into the paint matrix through FTIR spectra and SEM/FESEM analyses, which highlight strong molecular interactions and structural improvements. These findings suggest that graphene, when added in optimal amounts, can significantly enhance the physical and chemical properties of inorganic polymer paints, making it a promising material for applications in high-temperature environments and corrosion protection in industrial and construction fields. Testing adhered to ISO 834-1:2014 standards, ensuring reproducibility and practical relevance.
