Electrospinning is a very simple and versatile process by which polymer nanofibers with diameters ranging from a few nanometers to several micrometers can be produced using an electrostatically driven jet of polymer solution or polymer melt. Significant progress has been made in this process throughout the past few years and electrospinning has advanced its applications in many fields, includin...

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 R...

Crater-like electrospinning is a novel and cost-effective method for the mass scale production of nanofibers. The gas channel in the polymer solution plays a key role to produce a bubble Taylor cone or a crater-like Taylor cone, which is the key to eject the thin fluid jets (finally solidified into nanofibers) in electrospinning process. However, the formation mechanism of gas channel of crater...

Very thin liquid jets can be obtained using electric field, whereas an electrically-driven bending instability occurs that enormously increases the jet path and effectively leads to its thinning by very large ratios, enabling the production of nanometre size fibres. This mechanism, although it was discovered almost one century ago, is not yet fully understood. In the following study, experiment...

poly(vinylidene fluoride) (pvdf) fibers with two molecular weights were prepared via electrospinning process. in this process, the concentration of spinning depended drastically on the gelation process. also, it was experimentally smaller than obtained concentration in the solution entanglement number approach (sena). proof of this incompatibility was explained by the properties of pvdf and its...

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...
