Surface Characterization of Chinese Fir/TiO2 Composite
Small samples of Chinese fir/TiO2 composites were prepared by sol-gel method and MWLPD (microwave assistant liquid phase deposition) method for the first time. The surface of samples were analyzed by Fourier transform infrared (FT-IR) and X-ray photoelectron spectroscopy (XPS), and the microstructure and Ti distribution of samples was observed by scanning electron microscopy and energy dispersive spectroscopy (SEM-EDS). Results show that Ti is not only distributed on the composites surface, but also go into the inside wood. The composites surfaces are covered with pure TiO2. Activities of composites are increased considerably for the oxygen content and number of oxygen containing groups on there surfaces are increased considerably.
