THERMOELECTRIC BEHAVIOR OF NON CONDUCTING / CONDUCTING POLYMERIC MATERIALS

Abstract

As on the increasing energy crisis, large amount of heat are reported to be lost at low temperatures (up to 250 oC), that can reach more than 70 % of the total waste heat, the market is motivated for seeking of new materials for low temperature thermoelectric applications (LTTA). Organic materials, with their well-known properties of light weight, abundancy, versatility, low cast, ease of synthesis and processing, low thermal conductivity, in addition to eco-friendly and sustainability, show large findings in LTTP with their additional superior adjustment to be semiconducting / conducting moderate temperature stable materials (up to 300 oC). However all of these advantages, lower values of figure of merit were recorded for polymers and polymer composite that motivates for deep study of thermoelectric properties of polymers for the aim of understanding and developing new methodologies for organic thermoelectric materials.
