Plasma Polymerization on Hydroxyapatite Powders to Increase Water Dispersability for Biomedical Applications

The modification of hydroxyapatite powder using cold plasma. is described. This modification can be used to improve hydroxyapatite water dispersability and to control calcium release. A downstream, and a fluidized bed reactor have been successfully set-up to perform the surface treatment on hydroxyapatite. The advantages and drawbacks of both systems are presented.
