Organic thermoelectric (OTE) materials have applications as sustainable energy conversion materials. Use of conjugated polymer/carbon nanotube composites has increased thermoelectric efficiency, but quantitative and systematic analysis on the conjugated polymer in composites is difficult due to their non-covalent bonded nature and the complexity of heterogeneous systems. We analyzed systematically how morphology of conjugated polymers and their charge transport mechanism affect thermoelectric parameters of the composites, and found that high mobility conjugated polymer with a planar polymer backbone chain can increase electrical conductivity and thermal conductivity. As a result, we revealed that the structural properties of conjugated polymers outweigh the effects of chemical treatment, including doping, in composite systems. |
