Abstract

The purpose of this research was to create polycaprolactone nanocomposite coating - fluor apatite nanoparticles doped with silicon and magnesium, as well as polycaprolactone coating on the alloy in order to improve and modify the biological properties of this alloy. For this purpose, nano composite coating and polycaprolactone coating were first created by immersion methode. Then the physical, corrosion and biological properties of the coating created by different methods were investigated. The results indicated the creation of a uniform nanocomposite coating with a thickness of about 6.26 micrometers, with appropriate structure and phases, and an increase in roughness by adding nanoparticles to the polycaprolactone coating. Electrochemical measurements Ti6Al4V showed that the sample coated with polycaprolactone with nanoparticles has polarization RP=5.349×105 Ωcm2 resistance, which is higher than the sample coated with caprolactone with polarization resistance RP=1.191×105 Ωcm2 and the sample without coating with polarization resistance RP=5.2453×104 Ωcm2. Cytotoxicity test showed the non-cytotoxicity of the coatings. Also, the cell growth and proliferation of the sample with nano composite coating compared to the sample without coating has a statistically significant difference. Cell adhesion on the sample with nanocomposite coating was also much better than the sample without coating and the sample with polycaprolactone coating.
