Wettability Control: Controlling Wettability for Improved Corrosion Inhibition on Magnesium Alloy as Biomedical Implant Materials (Adv. Mater. Interfaces 8/2016)

TZ51 Magnesium alloys are ideal biomedical implant materials. But the poor corrosion property of magnesium alloys limits their clinical applications. Inspired by nature, for example the lotus leaf which exhibits excellent superhydrophobicity, Yan Liu and co-workers prepare special wettability surfaces including a superhydrophilic surface and a superhydrophobic surface in article number 1500723. The superhydrophobic surface exhibits excellent corrosion resistance property compared with the untreated Mg alloy substrate and superhydrophilic TZ51 magnesium alloy in Hank's simulated body fluid. The superhydrophobic magnesium alloy may provide a new method to solve the corrosion problem of Mg alloys as biomedical implant materials.
