Plasma dust can be one product of plasma polymerization. When polymerizatio
n occurs on the surface of a substrate, the product is a film; when polymer
ization occurs in the plasma volume, the product is plasma dust. Film and d
ust are different products with different chemical and physical characteris
tics. Plasma dust is composed of many small spheres with diameters ranging
from 0.2 to 0.5 mum. (C) 2000 Elsevier Science B.V. All rights reserved.
