Electrospinning is a simple and versatile technique that relies on the electrostatic repulsion between surface charges to continuously draw nanofibers from a viscoelastic fluid. Electrospinning can generate nanofibers with a number of secondary structures. Surface and/or interior of nanofibers can be functionalized with molecular species or nanoparticles during or after an electrospinning proce...

There is a need for polymeric hydrogen/air fuel-cell membranes that can efficiently conduct protons at moderate to high temperatures for wet and dry gas feeds. The US Department of Energy (DOE), for example, set an exceedingly stringent preliminary target for membrane conductivity, 0.10 Scm 1 at 120 8C and 50% relative humidity (RH). Herein, we describe the fabrication and basic properties of o...

Abstract Electrospinning is a common and versatile process to produce nanofibers deposit them on collector as two-dimensional nanofiber mat or three-dimensional (3D) macroscopic arrangement. However, 3D electroconductive collectors with complex geometries, including protruded, curved, recessed regions, generally caused hampering of conformal deposition incomplete covering electrospun nanofibers...

Background and aims: In nanofibrous filters, morphological properties, diameter of fibers and porosity percent of media are the most filtration characteristics. Therefore, the present study aimed to optimize the electrospinning parameters for reaching to the desired values of the mentioned filter characteristics. Method: For this purpose, a study design was prepared using response surface me...

Abstract Electrospinning is a relatively simple technique for producing continuous fibers of various sizes and morphologies. In this study, an intrinsically hydrophilic poly(3-hydroxybutarate- co -3-hydroxyvalerate) (PHBV) biopolymer strain was electrospun from solution under optimal processing conditions to produce bilayers beadless micro-fibers beaded nano-fibers. The fibrous mats produced th...

Electrospinning has received a lot of attention in recent years because it can create nonwoven nanofiber webs with high surface area and porosity. However, the typical needle syringe-based electrospinning systems feature poor productivity that limited their usefulness industrial field. Here, current developments creation nanofibers employing nonconventional methods, such as needleless syringele...
