Abstract
In this study, inhibition of magnesium alloy by Graphene oxide nanoparticles/polythreonine polymer as a nano-coating and also by different concentrations of food preservation as potassium sorbate to protect AZ91E Mg alloy as new temporary implants for gastrectomy applications from surface degradation process when surround with corrosive environments. This nano-coating as a novel one is decomposable and has bio-viability possessions. The results for sorbate shows that the higher concentration of potassium sorbate, the most corrosion resistance of the magnesium implants staples.Various electrochemical measurements were utilized for corrosion performance estimation of Mg alloy in peritoneal fluid with time of dipping. It was recognized that the nano-coating is fixed for 20 days giving unexpected high corrosion resistance. All experimental outcomes were verified by scanning electron microscope (SEM) and Energy dispersive X-ray (EDX) techniques. Moreover, in vitro antibacterial, and cytotoxicity of metal with and/or without coating utilizing MTT assay for cell viability analysis were achieved
