“…[81] In order to obtain shorter electrospun fibers for inhalation application a novel fiber cutting technique was developed based on lithography. [82] Here, polymers with double bonds, polybutadiene (PB) and a block copolymer of polystyrene and PB (Styrolux) were employed together with a photo cross-linker (PC) and photo initiator (PI) for obtaining oriented short electrospun fibers. Also, known photochemistry of coumarin ([2 þ 2] cycloaddition reaction) was utilized for making short electrospun fibers.…”

Electrospinning of nanofibers has developed quickly from a laboratory curiosity to a highly versatile method for the preparation of a wide variety of nanofibers, which are of interest from a fundamental as well as a technical point of view. A wide variety of materials has been processed into individual nanofibers or nanofiber mats with very different morphologies. The diverse properties of these nanofibers, based on different physical, chemical, or biological behavior, mean they are of interest for different applications ranging from filtration, antibacterial coatings, drug release formulations, tissue engineering, living membranes, sensors, and so on. A particular advantage of electrospinning is that numerous non‐fiber forming materials can be immobilized by electrospinning in nanofiber nonwovens, even very sensitive biological objects such as virus, bacteria, and cells. The progress made during the last few years in the field of electrospinning is fascinating and is highlighted in this Feature Article, with particular emphasis on results obtained in the authors' research units. Specific areas of importance for the future of electrospinning, and which may open up novel applications, are also highlighted.

“…A large number of advanced techniques have been developed to fabricate 1D nanostructures with well‐controlled morphology and chemical composition. Among these methods, electrospinning seems to be the simplest and most versatile technique capable of generating 1D nanostructures (mainly nanofibers; other types of 1D nanostructure, such as nanorods, can be cut from nanofibers by special methods19, 20) from a variety of polymers 21–28. Compared to the commercial mechanical spinning process for generating microfibers, electrospinning mainly makes use of the electrostatic repulsions between surface charges to reduce the diameter of a viscoelastic jet or a glassy filament.…”

This Review provides an overview of the synthesis of one-dimensional (1D) composite nanomaterials by electrospinning and their applications. After a brief description of the development of the electrospinning technique, the transformation of an inorganic nanocomponent or polymer into another kind of polymer or inorganic matrix is discussed in terms of the electrospinning process, including the direct-dispersed method, gas-solid reaction, in situ photoreduction, sol-gel method, emulsion electrospinning method, solvent evaporation, and coaxial electrospinning. In addition, various applications of such 1D composite nanomaterials are highlighted in terms of electronic and optical nanodevices, chemical and biological sensors, catalysis and electrocatalysis, superhydrophobic surfaces, environment, energy, and biomedical fields. An increasing number of investigations show that electrospinning has been not only a focus of academic study in the laboratory but is also being applied in a great many technological fields.

“…Physical methods use mechanical force or heat to break the continuous fibers into short fibers (Yoshikawa, Zhang, Zawadzak, & Kobayashi, 2011). Conventional methods such as grinding, milling, and cutting have been widely reported to mechanically break fibers into short fibers (Luo, Stride, Stoyanov, Pelan, & Edirisinghe, 2011;Stoiljkovic & Agarwal, 2008). Ultrasonication based on collapsing bubbles has recently emerged as an alternative method (Huang et al, 2009).…”

From a structural perspective, an ideal scaffold ought to possess interconnected macro pores with sizes from 10 to 100 μm to facilitate cell infiltration and tissue formation, as well as similar topography to the natural extracellular matrix (ECM) which would have an impact on cell behavior such as cell adhesion and gene expression. For that purpose, here we developed a fabrication process to incorporate electrospun short fibers within freeze‐dried scaffolds for tissue engineering applications. Briefly, PCL short fibers were first produced from electrospun fibers with ultrasonication method. They were then evenly dispersed in gelatin solution and freeze‐dried to obtain fiber incorporated scaffolds. The resulting scaffolds exhibited hierarchical structure including major pores with sizes ranging from 50 to 150 μm and the short fibers dispersed in the thin walls of major pores, mimicking the fibrous feature of natural ECM. The short fibers were proven to modify the mechanical properties of scaffold and to facilitate cell adhesion and proliferation on the scaffold. As a promising scaffold for tissue engineering and regenerative medicine, the fiber incorporated scaffold may have further biomedical applications, in which the short fibers can act as drug release vehicles for growth factors or other biomolecules to promote vascularization.
