FIELD: 3D printing.
SUBSTANCE: production of conductive filament, from which it is possible to produce flexible electronic devices for various purposes, capable of numerous cyclic deformations, using 3D printing by FDM technique. The conductive filament based on thermoplastic polyurethane for printing flexible electronic devices contains a mixture of modified carbon nanoparticles of various morphological structures, which uses carbon nanotubes and graphene in the following ratio of the specified ingredients, parts by weight: thermoplastic polyurethane (TPU) 90-95, carbon nanotubes (CNT) 2-5, graphene (G) 1-2.
EFFECT: making it possible to obtain a conductive material with a resistance of 0.1 Ohm⋅ m for 3D printers using FDM technique.
