4. Impregnation processes
4.1 General features of supercritical impregnation
Supercritical fluids are vectors/impregnating agents of choice because of their specific properties described above: a liquid-like density (200 to 900 kg · m –3 ), a gas-like viscosity (10 –5 to 9 × 10 –5 Pa · s), a diffusivity higher than in liquid phase (2 × 10 –8 to 7 × 10 –8 m 2 · s –1 ) and a very low interfacial tension. The transport of a solute, solubilized in a supercritical phase, inside a solid matrix is...
