摘要： Titanium dioxide(TiO2) has a good ultraviolet masking effect, antibacterial and photocatalytic function, so it is a good material for the preparation of organic inorganic composite materials, which can be widely used in industrial, food, environmental protection and other fields. In this paper, TiO2 hydrosol was prepared by sol-gel method with Butyl titanate(TBT) as precursors N, N-dimethyl acetamide ( DMAC) as the solvent, glacial acetic acid control pH, the ratio of the precursor and the solvent and the temperature effect reaction time and stability were studied. The optimum conditions is reaction temperature 80 degrees C, TBT/DMAC 1:4. This method can be used to prepare the composite materials and reduce influences of the later period.
