Nanofiber-based nonwoven mats produced in electrospinning setups are usually very fragile, which often limits their applicability. Yarns have the potential to enable incorporation of nanofibers into other materials using well-established techniques such as sewing, knitting, weaving and embroidering, thus broadening application nanofibers. Here, we review development continuous yarn processes. A...

A continuous near-field electrospinning NFES process has been developed to deposit solid nanofibers with orderly patterns over large areas. Before the onset of electrospinning, a bias voltage is applied to a semispherical shaped polymer droplet outside of a syringe needle, and a probe tip mechanically draws a single fiber from the droplet to initiate continuous NFES. Contrary to the conventiona...

anew and effective electrospinning method has been developed for producing aligned polymer nanofibers. the conventional electrospinning technique has been modified to fabricate nanofibers as uniaxially aligned array. the key to the success of this technique is the creation of a rotating jet by using a cylindrical collector in which the needle tip is located at its center. the unique advantage o...

Electrospinning is a simple and inexpensive process that produces continuous nanofibres from the submicron diameter scale down to the nanometer diameter scale through an electrically charged jet of polymer solution. Previously, most of the electrospinning experiments have been carried out using single-needle arrangements. However, the low fluid throughput in needle spinning has limited the indu...

We report on a continuous method for controlled electrospinning of polymeric nanofibers on two-dimensional (2D) and three dimensional (3D) substrates using low voltage near-field electrospinning (LV NFES). The method overcomes some of the drawbacks in more conventional near-field electrospinning by using a superelastic polymer ink formulation. The viscoelastic nature of our polymer ink enables ...

Electrospinning is applied to create continuous fibers with nanometer diameters through jetting polymer solutions in high electric fields. A drawback of this method, however, is the unstable behavior of the liquid jet, which causes the fibers to be collected randomly. So a critical concern in this process is to achieve desirable control. Studying the dynamics of the electrospinning jet will be ...

A core/sheath structured mesoporous silica nanofibre was prepared by coaxial electrospinning combined with the solvent evaporation induced surfactant assembly process. The characterization has given convincing evidence for the continuous highly ordered mesoporous structures, and its catalyst application was tested.

Electrospinning has emerged as an attractive technique for the fabrication of ultrafine fibres in micro-/nano-scale fineness: however, it remains a significant technological challenge to assemble aligned fibre arrays via an conventional electrospinning method due to the inherent whipping instability of the polymeric jet. We herein have first developed a simple modified electrospinning method wi...

Nowadays, polymer nanofibers have gained attention due to remarkable characteristics such as high porosity and large surface area to volume ratio. Among their fabrication methods, electrospinning technique has been attracted as a simple and reproducible approach. It is a versatile, simple and cost-effective technique for the production of continuous nanofibers with acceptable characteristics su...
