Size and surface charges of the PMMA and PVCs NPs from DLS measurements in water before and after washing.
| Polymer NPs | As synthesized | Washed and centrifuged (10,000 rpm) | ||
|---|---|---|---|---|
| D* (nm) | Ζ** (mV) | D* (nm) | Ζ** (mV) | |
| PVC | 120 ± 18 | −39.3 | 125 ± 18 | −26.4 |
| PMMA | 140 ± 16 | −26.8 | 140 ± 16 | −24.6 |
*D: Hydrodynamic diameter (nm).
**Z: Zeta-potential (mV), PDI values where 0.05 for PVC and 0.07 for PMMA NPs.
