In this study the effect of different shape carbon nanofillers by means of carbon nanotubes (1D) and graphene sheets (2D) on morphology, mechanical and electrical properties of poly(etylene terephthalate) based composite fibers was investigated. The amount of carbon nanotubes that were utilized to prepare the conductive fibers was 5wt.%, whereas the amount of graphene sheets was only 2.5wt.%. The masterbatches were prepared by Institute of Materials Science and Engineering. The polyester electro conductive fibers with carbon nanofillers and preliminary characteristic of synthesised nanocomposites were prepared by Torlen Sp. z o.o. in the course of a joint research project MNT ERA NET. The results show that both nanofillers can be incorporated into PET matrix with good dispersion. It was seen that PET nanocomposites demonstrated better mechanical performance especially seen in the tensile modulus.
