Fabrication and Properties of MWNTs/PANI/PVDF Composite Thermoelectric Materials
Abstract: For the development of new organic polymer thermoelectric materials, multi-walled carbon na-notubes (MWNTs), conducting polyaniline (PANI) and polyvinylidene fluoride (PVDF) polymer materials were ultrasonic mixed with different weight ratio and sprayed them to the surface of polyethylene terephthalate (PET) plastic sheets. A new-type MWNTs/PANI/PVDF polymeric ther- moelectric composite coatings was prepared. And the test showed that the synthesized composite thermoelectric coating materials were of interest for several reasons. 1) For the introduction of one-dimensional conducting pathways of the MWNTs and the PANI conductive particles, the elec-trical conductivity of composite is dramatically increased. 2) By adding the MWNTs and PANI particles into the PVDF polymer, a lot of interfacial potential barriers such as tube-tube junctions and scattering point for phonon and lower energy electrons among the MWNTs, PANI particles, and the PVDF polymer were introduced into composite matrix. As a result, the Seebeck coefficient and ZT value of the composite thermoelectric materials were enhanced obviously than the corresponding data of simplest carbon nanotube based organic thermoelectric composites. The research results could provide the important basis for the applications of new-type composite thermoelectric materials.
