aphrite-
Ha possesses well biocompatibility, which has been discovered through test and in clinical application. however, the relatively large dissolution or resorption rates of ha will result in the failure of the implants. fluoridated hydroxyapatite ( hfa ) in whose structure f " occupies partially the position of oh " in ha, is expected to be more resistant to body fluid and less soluble than ha and still possess almost the same bioactivity as ha
生物活性羥基磷灰石薄膜（ ca _ （ 10 ） （ po _ 4 ） _ 6 （ oh ） _ 2 ， ha ）廣泛地應用於鈦合金硬組織種植體表面改性，臨床應用發現ha薄膜具有很好的生物相容性，但是ha薄膜在體內溶解速度有時可能會過快，引起種植體在體內失效，因此， ha薄膜長效性方面有待于提高。However, in order to meet the mechanical and bioactive requirements, the challenging tasks for preparing the composites are how to prevent ha derived from aqueous environment from agglomeration, and how to disperse the ha particles in the polymer well
用表面修飾的化學方法，也只能在一定程度上緩解二次團聚的發生。在經過深入的文獻查閱和前期研究工作基礎上，本文提出採用有機介質中直接制備羥基磷灰石的方案。
