Abstract
The present invention relates to a method for coating polymethylmethacrylate (PMMA)-based co-polymer beads with nano-calcium phosphate. The method includes synthesizing the PMMA-based co-polymer beads containing hydroxyl pendant group, reacting the calcium salt and phosphate solution with the hydroxyl pendant group on the PMMA-based co-polymer beads, and thickening of the nano-calcium phosphate coating on the PMMA-based co-polymer beads.
