| 제목 | Fabrication of calcium phosphate-chitosan coating on Ti substrate for dental implants |
| 초록 | Chitosan (Chi) and bovine serum albumin (BSA) were coated as a coating layer on commercially pure titanium (cp-Ti) to improve bioactivity. The calcium phosphate (CaP) coating by soaking in modified simulated body fluid (m-SBF) solution was prepared. It was observed that the incorporation of BSA significantly modified the morphology, composition, and crystallinity of the CaP coating. The coating structure and its surface morphologies were determined by X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy. The calcium phosphates formed on chitosan and BSA spin coated substrate were ~ 350 nm size controlled materials. This provides not only the strong bonding of the apatite layer to the substrates but also a uniform gradient of stress transfer from coating materials to the Ti-substrate. This research was supported by the National Research Foundation of Korea (NRF) and grant funded by the Korea government (MSIP) (No. 2017R1A2B1012074). |
