310 HIGH PERFORMANCE POLYMERS
The electrically conductive composites prepared
by these methods are not sufficiently conductive for
shielding of electromagnetic interference. Still more
effective in producing conductive aramids is electro-
less plating. A high electrically conductive fiber that is
impregnated with metal complexes using supercritical
carbon dioxide is obtained.
The metal complexes are activated by reduction
in hydrogen and then immersed into an electro-
less plating solution. The process has been using
palladium(II)-hexafluoroacetylacetonate. The palla-
dium complex can be activated in the absence of
hydrogen [76]. This reduces the risks of
