Special Issue Information

Dear Colleagues,

Chitosan, a derivative of the natural polysaccharide chitin, has biocompatibility, biodegradability (which applies both to the polymer and the products of its biodegradation), bactericidal activity, an absence of toxicity, and high sorption characteristics. Solubility in dilute solutions of acids and good fiber-forming properties facilitate the processing of this polymer into fibers and nanofibers. Due to such properties, chitosan-based fibrous materials have attracted much attention for applications in cosmetology, cell-replacement technologies, and medicine including tissue engineering. The application of yarn or threads containing chitosan fibers makes it possible to obtain textile materials with improved hygienic characteristics and high bactericidal properties. Modifying chitosan-based materials with other kinds of polymers or nanoparticles can contribute to the expansion of their application areas.

The objective of this Special Issue, “Chitosan-Based Fibers and Nanofibers”, is to focus on actual research topics related to chitosan-based fibrous materials. It covers chitosan or chitosan blend fibers produced by wet spinning and chitosan-based nanofibers obtained by electrospinning, as well as other kinds of textile materials based on them. It involves fiber processing; the study of their structure, mechanical, physical, and biological properties; and composite or physical modification. Significant attention is paid to the application of the obtained chitosan-based fibrous materials.

Influence of Thermal Treatment and Acetic Acid Concentration on the Electroactive Properties of Chitosan/PVA-Based Micro- and Nanofibers

This study presents, for the first time, a comprehensive investigation of the influence of pre- and post-fabrication parameters for the electroactive properties of electrospun chitosan/PVA-based micro- and nanofibers. Chitosan/PVA fibers were fabricated using electrospinning, characterized, and tested as electroactive materials. Solutions with different acetic acid contents (50, 60, 70, and 80 v/v%) were used, and the rheological properties of the solutions were analyzed. Characterization techniques, such as rheology, conductivity, optical microscopy, a thermogravimetric analysis, differential scanning calorimetry, a tensile test, and FT-IR spectroscopy, were utilized. Fiber mats from the various solutions were thermally treated, and their electroactive behavior was examined under a constant electric potential (10 V) at different pHs (2–13). The results showed that fibers electrospun from 80% acetic acid had a lower electroactive response and dissolved quickly. However, thermal treatment improved the stability and electroactive response of all fiber samples, particularly the ones spun with 80% acetic acid, which exhibited a significant increase in speed displacement from 0 cm−1 (non-thermally treated) to 1.372 cm−1 (thermally treated) at a pH of 3. This study sheds light on the influence of pre- and post-fabrication parameters on the electroactive properties of chitosan/PVA fibers, offering valuable insights for the development of electroactive materials in various applications.

This study focused on a potential application of electrically conductive, biocompatible, bioresorbable fibers for tubular conduits aimed at the regeneration of peripheral nerves. The conducting, mechanical, and biological properties of composite fibers based on chitosan and single-walled carbon nanotubes were investigated in this paper. It was shown that introducing 0.5 wt.% of SWCNT into the composite fibers facilitated the formation of a denser fiber structure, resulting in improved strength (σ = 260 MPa) and elastic (E = 14 GPa) characteristics. Additionally, the composite fibers were found to be biocompatible and did not cause significant inflammation or deformation during in vivo studies. A thin layer of connective tissue formed around the fiber. Full article
