Study on the surface modification of nano-TiO2

摘要：

　　KH550 modified ZnO/TiO2 was prepared.The surface of nano-TiO2 was coated with ZnO derived from Na2Zn(OH)4 via a heterogeneous nucleation process,and coupling agent KH550 was used to treat the surface of ZnO/TiO2.Transmission electron microscopy (TEM),X-ray powder diffraction (XRD),Fourier transform infrared (FT-IR) spectroscopy and Optical contact angle measuring instrument were used to characterize the effect of surface modification.The results showed that the surface of nano-TiO2 was coated by ZnO nanoparticles; After modified by the KH550,the modified ZnO/TiO2 showed better dispersion in water-toluene solution; and the surface of modified ZnO/TiO2 became more hydrophobic-lipophilic than that of modified uncoated nano-TiO2.
