Preparation, characterization, and properties of nano-TiO2/silk fibroin hybrid films by sol-gel processing
By sol–gel processing, the regenerated nano‐TiO2/SF (silk fibroin) hybrid films were synthesized using different ratios of TiO2 to SF. The experimental results revealed that the nano‐TiO2 particles were well dispersed in the regenerated SF. The diameter of the nano‐TiO2 particles processed by sol–ge...

| description | By sol–gel processing, the regenerated nano‐TiO2/SF (silk fibroin) hybrid films were synthesized using different ratios of TiO2 to SF. The experimental results revealed that the nano‐TiO2 particles were well dispersed in the regenerated SF. The diameter of the nano‐TiO2 particles processed by sol–gel method was about 80 nm. Through Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), X‐ray energy dispersive spectrometer (EDS), Thermogravimetric analysis (TGA), and Derivative thermogravimetry (DTG), the structures and properties of these hybrid films were characterized. The XRD measurement indicated that the crystal structures of the hybrid films were transited from typical Silk I to typical Silk II. However, it was found that excessive increase in the content of nano‐TiO2 led to the breakage of the crystal structures of the hybrid films. The FTIR and EDS analysis showed that new bonds were formed between the nano‐TiO2 particles and the SF. Through TGA and DTG, it was demonstrated that the heat transition temperature of the hybrid films was also enhanced. © 2007 Wiley Periodicals, Inc. J Biomed Mater Res, 2008 |
