英文摘要	A novel, efficient and cost-effective approach for preparing surface modified Sb(2)O(3)nanoparticles was developed by combination modification of cationic modifier cetyl trimethyl ammonium bromide (CTAB) and silane coupling agent KH-560 via high energy ball milling. In the process of compound modification, the modifier of CTAB was introduced into the system in order to assist the dispersion of bare Sb(2)O(3)nanoparticles prior to the modification of silane coupling agent KH-560. Then, the obtained Sb(2)O(3)nanoparticles were further modified by the modifier of KH-560 to decrease the hydroxyl density of Sb(2)O(3)nanoparticles surface. The successful compound modification of Sb(2)O(3)nanoparticles was confirmed and the Sb(2)O(3)nanoparticles modified by compound modifiers possess smaller particle size and larger grafting ratio than pristine Sb(2)O(3)nanoparticles and single functionalized Sb(2)O(3)nanoparticles. Additionally, the stability of dispersions in organic media, the zeta potentials in the modification system and specific surface areas of Sb(2)O(3)nanoparticles with different surface properties were investigated. The effect of amount and varieties of modifiers on the surface properties of Sb(2)O(3)nanoparticles has been discussed. The results show that the Sb(2)O(3)nanoparticles modified by compound modifiers are dispersed on a primary particle level with the diameter size of 58 nm and possess a perfect dispersibility. Besides, the higher absolute values of zeta potential and larger grafting ratio of nano-Sb(2)O(3)particles modified by compound modifiers demonstrate that the electrosteric stabilization has been achieved by a combination of electrostatic repulsion and steric stabilization.
