Abstract Scope Zinc (Zn)- magnesium (Mg) alloys are suitable candidates as biodegradable materials for surgical implants. Their biocompatibility has been previously studied through cell compatibility, cytotoxicity, dynamic blood clotting and other genetic and bacterial test. However, they still face disadvantages due to their strength and degradation velocity in vivo. In literature you find information to enhance their corrosion resistance using coatings such as poly(methyl methacrylate) (PMMA) through spin-coating technique lacking of a thick covalent bond between the polymer film and the alloy. To overcome this issue, we developed an approach using grafting-from technique. PMMA was coated on Zn-Mg alloys and its effect on corrosion resistance and biocompatibility was evaluated. A dense, stable and biocompatible PMMA film with a thickness up to 5 Ám that achieved complete surface coverage with a hydrophobic behavior, was made possible. Presented data will include ATR-FTIR, EDAX-SEM , AFM, and XRD results, while cross-sections were characterized using SEM.
