摘要

Ultradispersed powders of Cu-Sn alloy were processed by fluorinated polyethers of different compositions. X-ray photoelectron spectroscopy was used to show that a polymeric film no thicker than 2 nm was formed on the surface of particles as a result of processing. The film formed by fluorinated polyethers with a molecular mass of 3000 prevents the interaction of metal particles of Cu-Sn alloy with atmospheric oxygen and provides dielectric properties of the surface.
