Crystalline Domain Formation to Enable High-Performance Polymer Thermoelectrics Inspired by Thermocleavable Materials

Abstract: Improving the electrical conductivity is an important role in realizing high thermoelectric performance of solutionprocessable polymers. Herein, a simple and robust approach to boost the mobility and doping efficiency of a diketopyrrolopyrrolebased copolymer with the introduction of thermocleavable side chains (PDPPS-X, where X is the molar ratio of the thermocleavable side chains and alkyl chains) is first provided. Notably, the incorporated thermocleavable groups can be effectively removed after thermal trea… Show more

“…Meanwhile, the relationship of σ and S agrees well with Chabinyc’s empirical modeling for the D–A CPs that the absolute value of S decreased (increased) and σ increased (decreased) when their S changed its sign. According to the published papers, ,, the DPP-based D–A CPs were endowed by the DPP unit with semicrystalline properties that the strong molecular ordering requires a high doping concentration and a long doping time to be overdoped. Hence, the doped D–A CPs show almost little impact on the relationship of σ and S .…”

“…Generally, organic molecules exhibit low σ. Chemical doping is an effective way to improve the σ value, and a lot of doped OTEMs have been developed with high performance. For example, the performance of p-type doped poly­(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT/PSS) has been greatly improved, and the ZT of which has reached 0.42 . In addition, combination with inorganic fillers is also a good way to improve the conductivity, among which, single-walled carbon nanotubes (SWCNTs) have been regarded as one of the best ones. The pristine SWCNTs show p-type characteristics because of oxygen doping during the preparation and application process, nevertheless, high k and low performance limit their application.…”
