Preparation and Characterization of APTES Modified Bioglass
Bioglass (BG) panicles were treated by 3-aminopropyltriethoxysilane (APTES) in order to improve the interface compatibility with polymer materials.The surface structures of modified BG were characterized through Fourier transformed infrared spectroscopy with attenuated total reflectance accessory,thermogravimetric analysis,differential scanning calorimetry analysis and X-ray photoelectron spectroscopy.The results showed that APTES was successfully grafted on the surface of BG.The biomineralization properties of APTES modified bioglass were also studied through FTIR,XRD and SEM.Results showed that hydroxylcarbonateapatite (HCA) was formed on the surface of modified BG after soaked into SBF solution.It was shown that the APTES modified BG could possess good mineralization properties and could be intended as a composition of scaffolds for bone tissue engineering applications.
