Polymer: Flexible Transparent Electrode and Application ofFlexible
Thermoelectric ConversionPro. Jianyong OuyangDepartment of Materials
Science and Engineering, National University of SingaporeConducting
polymers were discovered in 1970s. Recent progress in conducting
polymers demonstrated their important applications, such as the
next-generation transparent electrode and thermoelectric materials.
Optoelectronic devices require at least one electrode to be transparent.
Indiun tin oxide is traditionally used as the transparent electrode of
optoelectronic devices. But ITO has problems of scarce indium on earth
and poor mechanical flexibility. Conducting polymers, carbon nanotubes,
graphene and metal wire grids have been proposed to be the transparent
electode materials. Among them,
poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) is promising to
be the next-generation transparent electrode material due to its
solution processability, low cost and high transparency in visible
range. However, the as-prepared PEDOT:PSS film obtained from PEDOT:PSS
aqueous solution usually has conductivity below 1 S cm-1, remarkably
lower than ITO. Here, I will present several novel methods to
significantly enhance the conductivity of PEDOT:PSS. The conductivity
can be enhanced to be more than 3000 S cm-1, which is higher than that
of ITO on plastic and comparable to ITO on glass. Moreover, highly
conductive PEDOT:PSS can have high thermoelectric properties. They can
be used for heat harvesting and cooling at low
temperature.报告人简介:欧阳建勇
