[a] Solid content of the nanocomposite in water, as determined by gravimetric analysis. [b] Determined by TGA analysis. [c] Measured from the volume fractions obtained on electron micrographs. [d] Particle diameter measured on electron micrographs. [e] Half width of the particle diameter distribution. [f] Shell thickness measured on electron micrographs. [g] Slope of the adsorption isotherm (no unit). [h] not determined.
