Special Issue Information

Dear Colleagues,

I have been asked by the Editor of Nanomaterials (MDPI) to coordinate a Special Issue entitled “Advanced on Electrospun Nanofibers and Nanocomposites”.

This Special Issue is motivated by the observed growing interests on the design, fabrication, modification, and application of electrospun nanofibers and nanocomposites. Electrospinning technology has been widely used in the preparation of a wide range of nanoscale fibers for applications such as high-strength composite materials, nanoelectronics, sensors, biomedical application, drug delivery, food packaging, catalysis, membrane filtration, and energy applications (energy conversion/storage).

The rapidly developing technique of electrospinning has gained a surging research interest since its reinvention in 1990s due to its capability of yielding continuous fibers with diameters down to the nanometer scale, from a single needle spinning process to coaxial needle, multi-needle or the advanced bubble spinning technique. Electrospun nanofibers have comprehensive advantages such as continuity, diverse material choice, controlled diameter/structure, possible alignment/assembly, three-dimensional (3D) fibrous structures, mass production capability and can also be used as a platform for multifunctional, hierarchically organized nanocomposite.

In general, this Special Issue is oriented toward all types of nanofibers and nanocomposites materials, fabrication, characterization and modifications, innovations in materials, and improvements in electrospinning technology and process control to allow consistent production of nanofiber mats, and advanced multiple functionalities (physical, chemical, and biological functionalities) in order to obtain novel nanofiber and nanocomposite materials.

Considering your prominent contribution in this interesting research field, I would like to cordially invite you to submit a paper to this Special Issue through the webpage of the journal (S.I. Progress in Electrospun Nanofibers and Nanocomposites). The manuscript should be submitted online before the deadline of the Special Issue. The submitted manuscripts will then be fast-track reviewed. I would very much appreciate it if you could inform me of your interest in a paper contribution at your earliest convenience. Full papers, communications, and reviews are all welcome.

For the first time, a systematic study to investigate the electrospinnability of cyclic olefin polymer (COP) was performed. Different solvents and mixtures were tested together with different electrospinning parameters and post-treatment types to prepare bead-free fibers without defects. These were successfully obtained using a chloroform/chlorobenzene (40/60 wt.%) solvent mixture with a 15 wt.% COP polymer, a 1 mL/h polymer solution flow rate, a 15 cm distance between the needle and collector, and a 12 kV electric voltage. COP fibers were in the micron range and the hot-press post-treatment (5 MPa, 5 min and 120 °C) induced an integrated fibrous structure along with more junctions between fibers, reducing the mean and maximum inter-fiber space. When the temperature of the press post-treatment was increased (from 25 °C to 120 °C), better strength and less elongation at break of COP fibers were achieved. However, when applying a temperature above the COP glass temperature (Tg = 138 °C) the fibers coalesced, showing a mechanical behavior similar to a plastic film and a low elongation at break with a high strength. The addition of a high dielectric constant non-solvent, N,N-dimethylacetamide (DMAc), resulted in a considerable reduction in the COP fiber diameter. Based on the cloud point approach, it was found that the use of DMAc and the solvent chloroform or chlorobenzene improved the electrospinnability of COP polymer solution. Full article

For this purpose, two different biopolymers, a low-melting point and fully bio-based synthetic aliphatic copolyamide 1010/1014 (PA1010/1014) and the microbially synthesized [...] Read more.
In this research, bio-based electrospun multilayered films for food packaging applications with good barrier properties and close to superhydrophobic behavior were developed. For this purpose, two different biopolymers, a low-melting point and fully bio-based synthetic aliphatic copolyamide 1010/1014 (PA1010/1014) and the microbially synthesized poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and food-contact-complying organomodified silica (SiO2) nanostructured microparticles, were processed by electrospinning. The production of the multilayer structure was finally obtained by means of a thermal post-treatment, with the aim to laminate all of the components by virtue of the so-called interfiber coalescence process. The so developed fully electrospun films were characterized according to their morphology, their permeance to water vapor and oxygen, the mechanical properties, and their water contact angle properties. Interestingly, the annealed electrospun copolyamide did not show the expected improved barrier behavior as a monolayer. However, when it was built into a multilayer form, the whole assembly exhibited a good barrier, an improved mechanical performance compared to pure PHBV, an apparent water contact angle of ca. 146°, and a sliding angle of 8°. Consequently, these new biopolymer-based multilayer films could be a bio-based alternative to be potentially considered in more environmentally friendly food packaging strategies. Full article
