Special Issue Information

Dear Colleagues,

Polymer composites are multicomponent systems that combine two or more components, in order to produce materials with properties that are superior to individual components. In recent years, composites containing nanoparticles of various shapes and nature have been of great interest. It is assumed that they have excellent properties, exceeding those of composite materials with macro-sized fillers. The creation of new nanocomposite materials should significantly improve the various properties of already widely known and practically used polymers. Such materials are of high demand in different fields of modern life.

The development of high-performance polymer fibers is very important for various fields and applications. Nowadays, the most common technologies for the production of industrial fibers from synthetic and natural polymers are melt- and wet-spinning. However, it is evident that the preparation of nanocomposite polymer fibers can be associated with noticeable difficulties; namely, the uniform distribution of nanoparticles in the polymer matrix, improving adhesion between the polymer and nanofiller, etc.

This Special Issue aims to collect contributions on all aspects of current scientific and technological advances related to the processing of nanocomposite polymer fibers. It is my great pleasure to invite all scientists to contribute their manuscripts which focus on the current state of knowledge, as well as progress in the manufacturing and performance of nanocomposite polymer fibers.

HDPE-based composite fibers filled by original and annealed carbon nanodiscs (oND and aND, respectively) were prepared by melt extrusion technology with high-temperature orientational drawing up to draw ratio DR = 8. The thermal properties of the obtained fibers were investigated by DSC and TGA methods. It was shown that the nanofillers can be influenced by high temperatures, at which the molecular mobility in the interlamellar regions became active, while the melting point and the crystallinity degree of the samples were not affected. Short- and long-term mechanical properties of the nanocomposite fibers were studied as well. Very rare mechanical testing of the knotted fibers was carried out and, as a result, a decrease of the knot strength up to 35% was detected. It was also revealed that the carbon nanodiscs do not reinforce the composite fibers and play a negative role in the creep processes, while the Young’s modulus can be improved by 2 times for the oriented samples.

HDPE-based nanocomposite fibers have been extruded from a melt and drawn up to draw ratio DR = 8. Two kinds of carbon nanodiscs (original ones and those exposed to additional annealing) have been used as fillers. Obtained nanocomposite fibers have been investigated with the help of different experimental methods: rheology, SEM and WAXS. It has been demonstrated that the annealed carbon nanodiscs possess a nucleation ability that finally leads to strong transformation of the material morphology. Full article

The fibers based on thermoplastic partially crystalline polyetherimide R-BAPB modified by vapor grown carbon nanofibers (VGCF) were prepared by melt extrusion, exposed to orientational drawing, and crystallized. All of the samples were examined by scanning electron microscopy, X-ray scattering, and differential scanning calorimetry to study how the carbon nanofiller influences on the internal structure and crystallization behavior of the obtained R-BAPB fibers. The mechanical properties of the composite R-BAPB fibers were also determined. It was found that VGCF nanoparticles introduced into R-BAPB polyimide can act as a nucleating agent that leads, in turn, to significant changes in the composite fibers morphology as well as thermal and mechanical characteristics. VGCF are able to improve an orientation degree of the R-BAPB macromolecules along the fiber direction, accelerate crystallization rate of the polymer, and enhance the fiber stability during crystallization process.

Hyaluronic acid, curcumin, and usnic acid are separately utilized as effective biological agents in medicine, and materials based on its blend are considered to have wider therapeutic effects than individual ones. In this study, for the first time, native hyaluronic acid-based fibers containing curcumin and usnic acid with an average diameter of 298 nm were successfully prepared by the electrospinning technique and characterized. Additionally, unstable and hydrophobic curcumin and usnic acid were loaded into the hydrophilic hyaluronic acid matrix without utilizing the activating (catalyzing) agents, resulting in the formation of an electrospinnable solution. Only the binary mixture deionized water—dimethyl sulfoxide (50:50)—was used as solvent. The presence of small amounts of dimethyl sulfoxide in the fibrous materials was expected to provide the materials with local anesthetic and antiseptic activity. The effect of electric voltage on the electrospinning process, diameter, and morphology of hyaluronic acid/curcumin/usnic acid fibers was investigated in detail. The impact of curcumin and usnic acid on the stability of fiber formation was observed. The investigation of fibers based on pure hyaluronic acid without additional polymers and with active pharmaceutical ingredients will lay the groundwork for the development of highly effective wound dressings and new drug delivery scaffolds.
