摘要：The surface of anatase TiO2 was modified by maleic andydride （MAH） γ, radiation. The properties of surface modified TiO2 were investigated by X-ray diffraction （XRD）, Fourier transform infrared spectroscopy （FT IR）, X-ray photoelectron spectrum （XPS）, thermal gravimetric analysis （TGA）, as well as transmission electron microscopy （TEM）. The results suggest that the MAH anchored on the surface of TiO2 through chemical bonding and the grafting ratio was approximately 2.7%. TEM image revealed that the modified particles had good dispersibility and compatibility with N,N-Dimethylformamide（DMF）, which facilitated to hinder the aggregation of TiO2 particles.
