Particle and Fiber Production of Polymeric Materials During the Rapid Expansion of Supercritical Fluid Solutions

摘要

Solute nucleation and condensation processes leading to the formation of powders and fibers during the rapid expansion of supercritical fluid solutions are discussed. Examples of polymeric powders and fibers produced during the initial investigations of this process as a method for materials preparation are presented. Future work in this area will involve investigation of additional solvent-solute system and theoretical modeling of the particle formation mechanism operating during the expansion process.
