Surface Organic Modification of SiO2 & Al2O3 Coated TiO2 Particles with Titanate Coupling Reagent
Abstract:
The surface organic modification of TiO2 particles with titanate coupling reagent,which was precoated with double layers of SiO2 and Al2O3,was studied.Experiments showed that the modified particles exhibited hydrophobic characteristics.The modification state of the particle surface was characterized by IR spectroscopic measurement,pyrolytic gas chromatography,thermogravimetric analysis and Xray photoelectron spectra.The titanate coupling reagent binding with the hydroxyl on the particle surface was analyzed.The surface characteristics of premodification and postmodification particles were compared.
