| Abstract |
|
Using supercritical or near-supercritical fluids as media for physical or
chemical transformations is an emerging technology for nanomaterials production.
The unusual properties of supercritical fluids—including tunable solvent
strength, high diffusivity, and low viscosity, as well as the ability to replace
toxic solvents—offer materials processing in supercritical fluids significant
advantages over conventional processes. Nanoparticles, nanowires, and thin solid
films with high purity, uniformity, and homogeneity can be prepared in supercritical
or near-supercritical fluids with minimum environmental problems. A number of
nanomaterials processing techniques including rapid expansion of supercritical
solutions (RESS), microemulsion reactions, supercritical fluid transport–chemical
deposition (SFT–CD), supercritical fluid transport–chemical vapor
deposition (SFT–CVD), supercritical fluid chemical deposition (SFCD), chemical
fluid deposition (CFD), and supercritical fluid immersion deposition (SFID) are
described.
