Title:
METHOD OF TREATING CONDUCTIVE POLYMER
Document Type and Number:
WIPO Patent Application WO/2007/099889
Kind Code:
A1
Abstract:
A method by which the conductivity characteristics and mechanical properties of
a fibrous conductive polymer can be easily improved. The method for conductive-polymer treatment
comprises immersing fibers of a conjugated conductive polymeric material having
a dopant added thereto in a treating liquid comprising ethylene glycol and/or
an aprotic solvent for a given time to improve the conductivity characteristics
and mechanical properties of the fibers. Especially when the fibers are PEDOT/PSS
fibers in which the conductive polymeric material is poly(3,4-ethylenedioxythiophene) (PEDOT)
and the dopant is poly(4-styrenesulfonic acid) (PSS), a significant conductivity-improving
effect is produced.
