Material impregnation is another significant application of scCO2 in nanotechnology. The supercritical fluid can be used to impregnate various materials, such as polymers and textiles, with nanoparticles. This process can enhance the properties of the base material, such as adding antibacterial, catalytic, or conductive properties. The low viscosity and high diffusivity of scCO2 allow for deep penetration and uniform distribution of nanoparticles within the host material.
