In this paper, carbon nanotubes (CNTs) and micro glass bubbles (GBs) have been incorporated into apolyamide6 (PA6) matrix to impart thermoelectric properties. The spaces created in the matrix by GBs allows theformation of “segregated” CNT network. The tightly bound CNT network, if controlled properly, can serve as aconductive path for electron transport, while prohibiting phonon transport, which would provide an idealconfiguration for thermoelectric applications. The CNTs and GBs were dispersed in a nylon-formic acid solution usinghorn sonication followed by coagulation in deionized water, and nanocomposite panels were fabricated using a hotpress. The performance of nanocomposite panels was evaluated from thermal and electrical conductivities and Seebeckcoefficient, and a thermoelectric figure of merit as high as 0.016 was achieved.clos
