High‐Performance n‐type Organic Thermoelectric Aerogels Toward Flexible Energy Harvesting and Sensing Devices

open access: yesAdvanced Electronic Materials, EarlyView.
An n‐type organic thermoelectric aerogel PB@CNF, based on PBFDO, is fabricated by a two‐step freeze‐drying process with cellulose nanofiber (CNF) as substrate. The aerogels can be used not only as temperature sensing and piezoresistive sensing, but also to form a flexible organic thermoelectric generator with the p‐type aerogel (PH@CNF) based on PEDOT ...
