以基于赖氨酸原位修饰法制备的氨基化纳米二氧化钛进行不同煅烧温度下的热稳定性分析。用 SEM和FT-IR表征手段分析了在不同煅烧温度下氨基化纳米二氧化钛的形貌及结构，用 DTA-TG测量了它们的热失重曲线。结果表明：500℃以下的煅烧不会对材料的形貌结构产生太大的影响，氨基基团仍然存在；并且经过300℃的高温处理后，它的稳定性也有一定程度的提高。

The amino nano-TiO2 was prepared by modification in situ and the thermal stability through calcinations was analysed at different temperatures.The materials were calcined at different tempera-tures and then characterized by Fourier Transform Infrared Spectroscopy (FT-IR)and Scanning Elec-tron Microscope(SEM).Thermal stability was investigated through DTA-TG.Consequently,calcination below 500℃ has no impact on the morphology and structure of materials,amino groups still exist;after calcination at 300℃,its stability has also improved.
