Abstract
Poly(3,4-ethylenedioxythio-phene):poly(styrenesulfonate) (PEDOT:PSS)
is a promising conductive polymer in future flexible applications.
To apply PEDOT:PSS into organic electronic devices, patterning processes
are essential. Here, two photolithographic patterning schemes are
introduced, namely fluorinated materials and silver interlayers. With
hydrofluoroethers (HFEs) solvents and fluorinated photoresist, PEDOT:PSS
can be patterned down to micro scales. Using a silver thin film to
protect PEDOT:PSS surface, traditional photolithographic materials
can be applied for PEDOT:PSS patterning. These two patterning processes
do not obviously influence the electrical characteristics of PEDOT:PSS,
and patterned conductive PEDOT:PSS is successfully applied to organic
light-emitting diodes (OLEDs) as anodes. These patterning schemes
can easily be used on large substrates, and high-resolution flexible
OLED strips are also demonstrated. These results imply that the proposed
PEDOT:PSS patterning schemes here have great potential to be employed
in organic electronic devices.
