Special Issue Information

Dear Colleagues,

Nanofibers have attracted a great deal of attention over the past two decades (or longer) due to their unique physical properties, and are exploited as promising materials for a wide range of applications, including air and liquid filtration, battery separator, acoustic insulation, and biomedical applications, such as drug delivery, wound healing, tissue engineering, barrier textiles, etc. Nanofibers from a rich variety of materials, including polymers, composites, and ceramics, can be easily prepared using simple methods, such as electrospinning. Other techniques are also available for generating nanofibers, with diameters ranging from 5 to 500 nm or higher, which are 102–104 times smaller than fibers prepared using traditional processing methods. With this background, many researchers have worked toward the development of nanofibers for various applications.

This Special Issue of Nanomaterials will attempt to cover the recent advancements in the fabrications and applications of these nanofibers.

Magnetic nanofiber has been widely applied in biomedical fields due to its distinctive size, morphology, and properties. We proposed a novel needleless electrospinning method to prepare magnetic nanofibers from the self-assembling “Taylor cones” of poly(vinyl pyrrolidone) (PVP)/Fe3O4 ferrofluid (PFF) under the coincident magnetic and electric fields. The results demonstrated that a static PFF Rosensweig instability with a conical protrusion could be obtained under the magnetic field. The tip of the protrusion emitted an electrospinning jet under the coincident magnetic and electric fields. The needleless electrospinning showed a similar process phenomenon in comparison with conventional electrospinning. The prepared nanofibers were composed of Fe3O4 particles and PVP polymer. The Fe3O4 particles aggregated inside and on the surface of the nanofibers. The nanofibers prepared by needleless electrospinning exhibited similar morphology compared with the conventionally electrospun nanofibers. The nanofibers also exhibited good ferromagnetic and magnetic field responsive properties. Full article

A novel polyacrylonitrile (PAN) nanofibrous membrane conjugated with platinum nanoparticles (PtNPs) was fabricated by electrospinning and electrostatic assembly techniques. In this procedure, PAN was electrospun with 3-aminopropyltriethoxysilane (APS) together as precursor materials. First, amine groups were introduced onto PAN nanofibers, and then the as-prepared negative-charged platinum nanoparticles (PtNPs) were conjugated onto the surface of the amino-modified PAN nanofibers uniformly by the electrostatic interaction-mediated assembly. The fabricated PAN–PtNPs hybrid nanofibrous membrane was further utilized to modify the glassy carbon electrodes and was used for the fabrication of a non-enzymatic amperometric sensor to detect hydrogen peroxide (H2O2). The electrochemical results indicated that, due to the uniform dispersion of PtNPs and the electrostatic interaction between amine groups and PtNPs, the fabricated PAN–PtNPs nanofibrous membrane-based electrochemical sensor showed excellent electrocatalytic activity toward H2O2, and the chronoamperometry measurements illustrated that the fabricated sensor had a high sensitivity for detecting H2O2. It is anticipated that the strategies used in this work will not only guide the design and fabrication of functional polymeric nanofiber-based biomaterials and nanodevices, but also extend their potential applications in energy storage, cytology, and tissue engineering.
