| Outline of Final Research Achievements |
An inorganic-organic hybrid film was prepared by an electropolymerization on the surface of magnesium alloys in order to control a corrosive speed of the degradable magunesium alloys. A conductive monomer, 2,3-Thiophenedicarboxaldehyde, and a supporting electrolyte, perchloric acid tetrabutyl, were dissolved in MMA and were mixed in a volume ratio of 1:1. Next, a nano-hydroxyapatite was added in the mixed solution. They were used as an electrolyte. The alloy and carbon rod were used as a cathode and anode, respectively, for the electropolymerization. The electrolyte was stirred under the electropolymerization. The treated surface was analyzed by EPMA, XPS, FTIR and AFM.
According to these results it can be concluded that PMMA film containing of nano-hydroxyapatite, which was bio active material, was formed on the surface of the alloy. Therefore, inorganic-organic hybrid film was prepared and could be designed to control the speed of the corrosion process of the alloy.
