Hydrodynamic sizes and zeta potentials of anatase, rutile and anatase/rutile mixture of n-TiO2 in water
n-TiO2 polymorph | Size range(nm) | Z-Average(nm) | Zeta potential(mV) |
---|---|---|---|
Anatase | 265 – 1335 | 637 | −16.7 ± 4.2 |
Rutile | 61 – 1152 | 432 | −31.6 ± 4.5 |
Mixture | 356 – 859 | 662 | −15.7 ± 4.9 |
Z-averages are calculated by the Zeta sizer software. The data for three replicate measurements.
