| Abstract: | In order to study the surface modification of TiO2,the effects of types and contents of coupling agent(including KH550,KH560 and KH570) and hydrolysis conditions on the modification were investigated.Several properties of modified powders,such as sedimentation volume,lipophilic degree,exhibited an excellent modification effect,especially with using KH570.Under the neutral pre-hydrolysis condition,the modification effect was better than under the acid and alkaline conditions.The microstructures of modified a... |
