2: POLY( p-XYLYLENE)S 57
can be associated with the gradient of nanoparticle
sizes.
A high photoconductivity has been demonstrated.
The photocurrent in the sample prepared in an electric
field of 10 kV cm
−1
may exceed the dark current by
two orders of magnitude [103].
2.5.4.5 Cobalt Nanocomposite Films
Nanostructured and planar films of poly(p-
xylylene) have been fabricated by an oblique angle
polymerization method. Subsequently, these films
were coated with cobalt by an electroless deposition
method [104].
The catalyticactivity of the cobalt has beenassessed
via the rate of hydrogen evolution by the hydrolysis of
an alkaline-stabilized sodium borohydride solution. ...
