Modification and characterization of titanium dioxide surface Available to Purchase

The surface character of titanium dioxide (rutile) was altered by surface modification. Silane coupling agents were used as modifiers. Physicochemical properties of the obtained products were evaluated. Effects of the modifier concentration on changes in hydrophilic/hydrophobic properties of the surface were estimated. The tendency to form primary and secondary agglomerate structures was defined using dynamic light scattering and examining morphology and surface structure with the use of scanning electron microscopy. Specific surface area and pore volume were also measured in unmodified and modified titanium white.
