deposited films, solution cast films, and nanofibers

2.3.1.6 Soft Magnetic Composites
Soft magnetic composite particles of reduced iron
coated with ultra-thin films of poly(p-xylylene) can
be prepared by a CVD polymerization [47].
IR spectroscopy indicates that the polymer covered
outside the reduced iron particles is poly(p-xylylene).
The thickness of polymer film is around 100 nm
as confirmed by transmission electron microscopy
(TEM). A TEM photograph is shown in Figure 2.5.
The resistance to thermo-oxidation of the compos-
ite particles is much
