Electric Conductive and Mechanical Properties of Fibers Based on Polylactide and Carbon Nanofiber

  • Published:
Fibre Chemistry Aims and scope

Using a twin-screw microextruder, fibers based on polylactide and carbon nanofibers (CNFs) were obtained with 4- and 6-fold orientational stretching. The electroconductive and deformation-strength properties of composite fibers were investigated depending on the concentration of the filler and orientational stretch ratio of the polymer. It is shown that with the introduction of low concentrations of CNF (~1 wt%) and with the use of additional high-temperature orientational stretching of the polymer by a factor of 4, it is possible to create composite polylactide fibers with knot-pull tensile strength increased by 20% and with electro-scattering properties.
