Figure S1. Partial titration curves obtained by adding Jeffamine 2070 solution (20 wt%) to the functionalized silica nanoparticles suspension for the preparation of NOHMs of different grafting densities (3.8, 2.5, 2.0 and 1.0 chain·nm−2).
Figure S2. Thermogravimetric curves of the NOHMs with different grafting densities (3.8, 2.5, 2.0 and 1.0 chain·nm−2). Mass[%] was calculated based only on the canopy portion of NOHMs.

Figure S3. Viscosity of NOHM-I-HPE-3.8 as a function of temperature. About 1 mL of NOHMs sample was used for the analyses and the viscosities were measured from 40 oC to 70 oC with a 5 o
C increment.
