The results of studies assessing the influence of the addition of carbon nanofillers, such as multiwalled carbon nanotubes (MWCNTs) and graphene oxide (GO) that differ in size and structure, on the molecular and supramolecular structure and properties of alginate fibers that might be prospective precursors for carbon fiber (PCF) industry are presented in this article. The investigation was carried out by Fourier transform infrared (FTIR) spectroscopy, wide-angle X-ray diffraction (WAXD), and tension testing. In the frame of the current study, two types of alginate fibers were examined and compared: alginic acid and calcium alginate fibers. Alginic acid fibers were formed by chemical treatment of calcium alginate fibers with hydrochloric acid due to the fact that Ca2+ ions presented in the fibers were expected to adversely affect the prospective carbonization process. This investigation brought important conclusions about the influence of nanofillers on the physical properties of the final material. Understanding the link between the incorporation of carbon nanostructures and a possible influence on the formation of ordered carbon structures in the precursor fibers brings an important opportunity to get insights into the application of alginate fibers as a prospective base material for obtaining cost-efficient carbon fibers.
