Abstract

This disclosure provides systems, methods, and apparatus related to thermoelectric polymer aerogels. In one aspect, a method includes depositing a solution on a substrate. The solution comprises a thermoelectric polymer. Solvent of the solution is removed to form a layer of the thermoelectric polymer. The layer is placed in a polar solvent to form a gel comprising the thermoelectric polymer. The gel is cooled to freeze the polar solvent. The gel is placed in a vacuum environment to sublimate the polar solvent from the gel to form an aerogel comprising the thermoelectric polymer.
