Development of PMMA-GO hybrid coatings applied as anti-corrosion coatings
摘要
The development of anti-corrosion coatings based on graphene has garnered significant interest due to graphene’s chemical and thermal stability, as well as its barrier properties, making it an ideal material for such applications. When dispersed within a polymeric matrix, graphene enhances coating efficiency by reducing the permeation of corrosive media. This study presents the synthesis of an anti-corrosion coating composed of a polymethyl methacrylate (PMMA) polymeric matrix combined with graphene oxide (GO) particles in three compositions. Results indicated that the S2 coating exhibited the highest corrosion resistance in well extraction pipes; however, elevated water temperatures led to a reduction in this resistance. The addition of 1 wt% of GO strengthened the polymeric matrix physically, resulting in improved microstructure cohesion and optimal corrosion resistance. Structural and morphological analyses were conducted using FTIR, SEM, and DSC/TGA techniques.
