英文摘要	In order to enhance the interface adhesion between polymer matrix and Sb2O3 nanoparticles, the surface of Sb2O3 nanoparticles was modified via the mechanochemical method and using different surfactants including stearic acid, coupling agent of organic titanate (NDZ-201) and silane coupling agent KH-560. The dispersibility, hydrophobicity, microstructures, particle size distributions, thermal stability and surface potential of the modified and unmodified Sb2O3 nanoparticles were characterized by transmission electron microscopy (TEM), surface contact angle measurement, x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analyzer, laser particle size analyzer and zeta potentiometer, respectively. The results show that the surface chemistry of the nanoparticles was grafted from hydroxyl groups to alkyl groups by reacting different surfactants with Sb2O3 nanoparticles and physical coating. Stearic acid can be effectively coated on the surface of Sb(2)O(3 )nanoparticles. Besides, the modified Sb2O3 nanoparticles have the better dispersibility than the unmodified Sb(2)O(3 )nanoparticles in octane due to the fact that the steric hindrance of modifier between nanoparticles prevents aggregation. The mean particle size of the modified Sb2O3 nanoparticles is smaller than that of the unmodified Sb2O3 nanoparticles. The mean particle size of Sb2O3 nanoparticles modified by 3 wt% KH-560 is 57 nm as a result of steric hindrance and lower surface potential. Furthermore, the water contact angle of Sb2O3 nanoparticles modified by 5 wt% stearic acid reached to 114 degrees.
