Abstract:
Stainless steel is one of the most widely used metals in the fabrication of metal implants. It seems necessary for implants such as stainless steel (SS) to have antibacterial properties. Therefore, in this study, zinc oxide (ZnO) flower-like structures were synthesized on the SS surface through hydrothermal methods. The effect of two parameters: surface chemical modification and concentration of seeding solutions (0.005 M and 0.01 M) on the morphology of synthesized ZnO was evaluated using scanning electron microscopy (SEM). Based on SEM images, sample which has chemically modified with piranha solution (3:1; sulfuric acid and Hydrogen peroxide) at 0.01M Zn(NO3)2 in isopropanol as a solvent was the best one because of desirable uniformity of flowerlike morphology and surface filling area of ZnO-. X-ray diffraction (XRD) tests showed that the mentioned sample contained ZnO wurtzite structures without any impurity. Surface modification and concentration of seeding solution has an impact effect on hydrothermal reaction condition.
