In the present work we investigated the localized photodoping process of po
lyaniline-emeraldine base/poly(vinylchloride) blends by high-energy photons
from a synchrotron source. The doped blend was characterized using optical
and electrical parameters. An abrupt increase of conductivity by four orde
rs of magnitude (10(-10) to 10(-6) Scm(-1)) was observed using an initial d
ose of 500 Jcm(-3). Lithographic patterns were recorded with micrometer res
olution, Copyright (C) 2000 John Wiley & Sons, Ltd.
