Nanocomposites from multi-walled carbon nanotubes (MWCNTs) mixed in polyethylene terephthalate (PET) matrix were prepared by melt processing method. Elastic modulus increased by increasing MWCNT content. Electrical conductivity revealed percolation threshold depending on MWCNT content and frequency. Small increase in thermal conductivity was also noticed. Obtained nanocomposites exhibited thermoelectric characteristics showing highest Seebeck coefficient S=9.73 V/K at 2 wt. % MWCNT content. Power factor and figure of merit increased by several orders of magnitude by increasing MWCNT content.
