Supplication of Supercritical Fluids in Preparation of Nano-particles

Since supercritical fluid has some unique characteristics: low viscosity, high density, better performance of mass transfer, heat transfer and dissolution, it has been proved to have great potential in the future development. The application of nano-particles in the fields such as magnetic materials, electronic materials and optical materials is very remarkable so that the preparation of nano-particles has been a rising area in the research of chemical engineering. This paper is mainly about the supplication of supercritical fluids in preparation of nano-particles.
