Scaled particle theory INDEX

A recent development in the production of polymer particles has created a revolutionary new technology for the production of submicron polymer particles from solution, In this experiment, generation and characterization of droplet streams with small (< 15 pm) average diameters have been used to create nano-polymer particles. This technique makes the initial volume of a dilute solution of any polymer material sufficiently small so that the solvent evaporation occurs on a very short time scale leaving behind a polymer particle. For micro and nano-scale generated polymer particles, the refractive index obtained from the data analysis is consistent with bulk (nominal) values and the level of agreement with Mie theory indicates that the particles are nearly perfect spheres.
