Abstract
The nanocomposite of a poly(methyl methacrylate)/silica containing calcium salt was synthesized through the sol-gel method. Methyl methacrylate was co-polymerized with 3-(trimethoxysilyl)propyl methacrylate and then it was co-condensed with tetraethyl orthosilicate and calcium nitrate tetrahydrate. The low crystalline hydroxyl carbonate apatite was successfully formed on its surface after soaking in simulated body fluid for 1 week at 36.5 °C. It implies that this nanocomposite may be used as a bioactive bone substitute or filler for the PMMA bone cement.
