Flexible and lightweight thermoelectric (TE) generators have attracted increasing interest for powering wearable electronics using the temperature difference between human body and ambient air. Conducting polymers or their based composite materials are suitable for such applications; however, most conducting polymers show p-type conduction, hence, until now almost all reported flexible TE generators, which use conducting polymers or their based composite materials, are single-carrier-type (p-type) leg devices, connecting alternatively p-type legs electrically in series with silver or other metals. In this paper, both p- and n-type flexible TE materials have been developed using polymers and single walled carbon nanotubes (SWCNTs). The p-type TE films are prepared by integrating SWCNTs into a high conductive poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) matrix, using a dilution-filtration method. N-type TE films with Seebeck coefficient about -35 mu V/K are realized by treating SWCNTs with polyethyleneimine (PEI), and an encapsulation process has been employed to effectively preserve its n-type characteristics. Benefited from the flexibility of both the substrate and the composite films, a flexible TE prototype composed of six p-n junctions connected in series has been fabricated to demonstrate TE voltage output and power generation. The output power from the prototype is 220 nW for a 50 K temperature gradient. (C) 2017 Elsevier Ltd. All rights reserved.
