The surface modification of nanometer ATO powder by coupling agent was investigated. Effects of reac-tion conditions such as the kinds of coupling agent, reaction temperature, reaction time, and content of coupling agent on the surface modification of nanometer ATO powder were systemically studied. FT-IR spectrums and thermal gravimetric a-nalysis (TGA) were employed to analyze the surface component and dispersion of the nanometer ATO powder before and after coupling modification. The results showed that the optimal condition was attained when using 2phr KH570 silane cou-pling agent with 80℃ reaction temperature and 5 hour reaction time The modified nanometer ATO Powder was suitable for polymer modification in heat resistance.
