Hybrid materials consisting of inorganic nanostructures embedded in conducting polymer matrices have emerged as promising systems for room temperature thermoelectric applications. They are attractive due to their intrinsic low thermal conductivities, the ability to engineer interfaces for energy filtering effects and phonon scattering, and their ability to take advantage of high-throughput and solution processable manufacturing. When synthesizing hybrid materials, one can think of them as a three phase system consisting of the organic material, the inorganic material, and the interface. Our goals revolve around controlling each of these components independently, and in this contribution, I will detail our recent efforts towards this end. Ultimately, we aim to develop an understanding of how to use solution-based synthesis to influence thermoelectric device properties.
