The interest in thermoelectric materials has grown in the last few years since new applications in energy harvesting on the rise. Recently, an increasing number of studies have reported on polymeric thermoelectric materials. It have advantages in the form of mechanical flexibility, low-cost synthesis, and solution processability over large areas such as wearable device. In this work, we optimize the power factor (α2σ) of the conducting polymer, especially poly(3,4-ethylenedioxythiophene):tosylate (PEDOT:Tos) by controlling its geometrical nanostructure. We controlled the geometry of PEO polymerization template that has sub-50nm nanostructure using PS-b-PEO block copolymer self-assembly. The BCP self-assembled nanostructure can form the confined geometry of PEO and help to increase crystallinity and alignment of PEDOT:Tos. Through this high crystalline PEDOT:Tos, we confirmed possibility that controlling crystallinity of conducting polymer can enhance thermoelectric properties. |
