Leaching of RB from RB@ORMOSIL matrices.
| Specimen * | Amount of Leached RB, µmol ** | RB Leaching, % | Actual Loading of RB in Matrices, µmol/g |
|---|---|---|---|
| RB1 | 19.1 | 45.2 | 5.47 |
| RB2 | 22.0 | 52.0 | 4.67 |
| RB3 | 8.6 | 20.4 | 7.83 |
| RB4 | 18.7 | 44.3 | 5.45 |
| RB5 | 15.5 | 36.7 | 6.37 |
| RB6 | 16.9 | 40.0 | 5.94 |
* In all the cases, the RB loading used for ORMOSIL synthesis was 0.073 mole % when calculated based on the total moles of silane precursors. ** Calculated on the basis of 42.2 µmol RB loaded onto the matrix.
