一种制备仿生生物活性钙磷涂层的新方法

A Novel Method for Preparing Biomimetic Bioactive Calcium Phosphate Coatings

摘要:

提出了一种在导电材料表面制备仿生生物活性钙磷涂层的新方法，即首先经阴极声电化学处理材料使表面带上含钙离子的功能化基团，然后浸入过饱和溶液，钙磷晶体在功能化表面上发生异相成核生长，从而形成薄膜或涂层。根据该方法，成功地在碳／碳复合材料表面制备了仿生五水磷酸八钙涂层，实现了生物惰性碳／碳复合材料表面生物活化改性。

Abstract:

A novel method for preparing biomimetic bioactive calcium phosphate coatings on the electric materials was put forward. In the method the functional groups containing calcium element were first grafted on the surface of the electric materials by sonoelectrochemical method. When the modified materials were dipped into supersaturated calcium phosphate solution for a period of time, the calcium phosphate crystal would grow on the surface. By this technology, bioactive OCP coating has been successfully prepared on carbon/carbon composites, and biomimetic activation was realized on bioinert carbon/carbon composites.
