Abstract
Process for passivating polymeric particles to prevent undesirable interaction with the environment. In particular, sputter coating of metal and surface treatment with aqueous solutions are shown to successfully passivate the particles, such as for example, toner particles, and prevent interaction between the particles and the epoxy embedding resin which causes artifacts, observed by transmission electron microscopy (TEM) imaging.
