Special Issue Information

Dear Colleagues,

With the development of nano-technology, nanomaterials have received extensive attention in the fields of environment, healthy, medical, detection, and energy, etc. From among various nanomaterials, nanofibers have recently been attracting a great deal of interest from researchers recently due to the variety of amazing characteristics they possess including large specific surface areas, high aspect ratio and pore volume, excellent pore interconnectivity, and superior mechanical performance. Electrospinning is the most common method to prepare nanofibers with diameters that range from several nanometers to hundreds of nanometers. Most importantly, nanofibers with unique composition, structure or function design may provide better stability, response, function, and integrality to a variety of applications, and these attributes can be achieved via electrospinning. Therefore, we are convinced that electrospun nanofiber have great potential applications in the future.

This Special Issue of Nanomaterials, entitled “Advance in Electrospun Nanofibers”, will concentrate on presenting the current state of the art of the use of nanofibers in various areas. Potential topics include, but are not limited to, advances in or studies in the following topics:

  1. Eletrospun nanofiber preparation principles and model analysis;
  2. Nanofiber-based sensor device;
  3. Nanofiber in the application of fuel cells;
  4. Nanofiber filter material;
  5. Nanofiber in piezoelectric and triboelectric nanogenerators.

We sincerely invite all the researchers to contribute to this Special Issue, which welcomes experimental and theoretical original research papers, communications, and reviews articles.

Owing to their excellent elasticities and adaptability as sensing materials, ionic hydrogels exhibit significant promise in the field of intelligent wearable devices. Nonetheless, molecular chains within the polymer network of hydrogels are susceptible to damage, leading to crack extension. Hence, we drew inspiration from the composite structure of the human dermis to engineer a composite hydrogel, incorporating dopamine-modified elastic fibers as a reinforcement. This approach mitigates crack expansion and augments sensor sensitivity by fostering intermolecular forces between the dopamine on the fibers, the hydrogel backbone, and water molecules. The design of this composite hydrogel elevates its breaking tensile capacity from 35 KJ to 203 KJ, significantly enhancing the fatigue resistance of the hydrogel. Remarkably, its electrical properties endure stability even after 2000 cycles of testing, and it manifests heightened sensitivity compared to conventional hydrogel configurations. This investigation unveils a novel method for crafting composite-structured hydrogels. Full article

Polylactic acid (PLA) is a biodegradable polymer made from natural sources, and its electrospinning (e-spinning) nanofiber membrane doped with antibacterial ingredients is widely used in the field of medical dressings. In this research, 9 wt% of rosmarinic acid (RosA) and 0.04 wt% of graphite oxide (GO) with synergistic antibacterial activity were introduced into the e-spinning PLA precursor solution, and the obtained PLA nanofiber membrane showed good antibacterial properties and wound healing effects. At the same time, a nonionic amphiphilic polymer, polyethylene glycol (PEG), was also introduced into this system to improve the hydrophilicity of the e-spinning membrane for wound healing application. The morphological characterization showed the RosA/GO and PEG did not affect the e-spinning of PLA. The tests of mechanical performance and wettability demonstrated that PEG and RosA/GO incorporated in PLA have migrated easily to the surface of the fiber. The e-spun PLA/PEG/RosA/GO membrane showed good antibacterial activity and promoted initial wound healing quickly, which would be a promising application in wound dressing. Full article
