Preparation of calcium phosphate on chitosan- and BSA-coated substrates |
| 초록 |
To improve bioactivity, Chitosan (Chi) and bovine serum albumin (BSA) were coated as a coating layer on commercially pure titanium (cp-Ti) by spin coating method. The calcium phosphate (CaP) coating by soaking in modified simulated body fluid (m-SBF) solution was prepared. 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-coated substrate were ~ 350 nm size controlled materials. It was observed that the incorporation of BSA significantly modified the morphology, composition, and crystallinity of the CaP coating. This composite coating 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) grant funded by the Korea government (MSIP) (No. 2019R1A5A2027521). |
