Abstract:

This article presents the manufacturing conditions of polyacrylonitrile (PAN) fibres with ferromagnetic properties. These properties are obtained as the result of incorporating a Fe3O4 nanoaddition into the fibre-grade matter at the stage of preparing the spinning solution. The influence of the solidification conditions and the deformation distribution in the two-stage drawing process on the fibres’ tensile strength properties was determined. The supermolecular structure, the porosity, the ferromagnetic properties, and the distribution of the nanoaddition on the surface of the fibres formed under the given conditions were characterised.
