摘要：
A poly (acrylic acid)-titanium oxide (PAA-TiO2) was successfully prepared and verified by particle size distribution analyzer and transmission electron microscopy. The fabrication of self-assembly films from diazoresin and PAA-TiO2 was confirmed by UV-vis measurement. Thickness of the films was regularly increased with the layer-by-layer self-assembly process. Furthermore, the ionic bonds in the polymer films converted to covalent bonds under UV irradiation, with the decomposition of diazoresin group. Finally, the surface morphology of the films was investigated by atomic force microscopy (AFM). Results indicate TiO2 were uniformly dispersed in thin films by the self-assembly process.
