Enhanced thermoelectric performance of PEDOT with different counter-ions optimized by chemical reduction

Abstract

The thermoelectric properties of ICPs doped with different counterions have been investigated. An experimental value of ZT = 0.22 has been obtained for PEDOT:bis(trifluoromethylsulfonyl)imide.

Photoinduced p‐ to n‐type Switching in Thermoelectric Polymer‐Carbon Nanotube Composites

“…[ 12,13 ] Interestingly, the thermal conductivity of bulk polymers as well as conjugated macromolecules can be tuned by controlling molecular orientation. [14][15][16] In order to increase the modest electrical conductivity of polymers, a number of strategies have been proposed, including careful doping, [ 4,11,[17][18][19][20][21] making composites of polymers with conductive fi llers such as CNTs, [22][23][24] or fabricating multilayer composite A broad range of organic electronic applications rely on the availability of both p-and n-type organic semiconductors, and the possibility to deposit them as sequential layers or to form spatial patterns. Examples include transport layers in diodes (OLEDs, photovoltaics, etc.…”

Review—Towards the Next Generation of Thermoelectric Materials: Tailoring Electronic and Phononic Properties of Nanomaterials

“…Different approaches, such as wet techniques, 2 blade-coating, 3 electrochemistry, 4 melting, 5 etc. have been used to modify the doping, 4 fabricate composites, 6 and tailor other characteristics that have been studied for their optimization and to understand how nanostructuring of organic materials affects their thermoelectric performance.…”

Then, two conductive polymers, namely Poly(3,4-ethylendioxitiophene) (PEDOT) and Poly(3-hexylthiophene-2,5-diyl) (P3HT) will be described in detail, showing not only the advances obtained in their thermoelectric performance from a fundamental point of view, gaining a new insight into the behavior of such polymers, but also the implementation of device prototypes which show the potential of these materials.…”

A Ni3S2-PEDOT monolithic electrode for sodium batteries

“…This problem can be alleviated if an electroactive polymer layer with good binding compatibility was introduced to protect Ni 3 S 2 . Therefore, much attention has been paid to Poly(3,4-ethylenedioxythiophene) (PEDOT) because of its high stability, mechanical flexibility and excellent conductivity [20][21][22].…”
