Room-temperature synthesis and characteristics of nanocrystalline TiO2 on mica by homogeneous precipitation

초록

Nanocrystalline TiO2 layers were synthesized onto a mica substrate using a room temperature homogeneous nucleation method. The synthesis was controlled by optimizing the precipitants, the pH, the reaction temperature, the reaction time, and the stirring rate. The TiO2 layers were characterized by photospectrometry, X-ray diffraction, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high-resolution electron microscopy (HREM). The layers were well synthesized even at room temperature, which resulted in pigments having a strong interference color.
