Electrospinning is a simple and convenient technique to produce polymer fibers with diameters ranging from several nanometers to a few micrometers. Different types of polymer fibers have been prepared by electrospinning for various applications. Among different post-treatment methods of electrospun polymer fibers, the annealing process plays a critical role in controlling the fiber properties. ...

Superhydrophobic surface, as a promising micro/nano material, has tremendous applications in biological and artificial investigations. The electrohydrodynamics (EHD) technique is a versatile and effective method for fabricating micro- to nanoscale fibers and particles from a variety of materials. A combination of critical parameters, such as mass fraction, ratio of N, N-Dimethylformamide (DMF) ...

Cellulose nanocrystals (CN) were used to reinforce nanofibers in composite mats produced via electrospinning of poly(vinyl alcohol) (PVA) with two different concentrations of acetyl groups. Ultrathin cross-sections of the obtained nanocomposites consisted of fibers with maximum diameters of about 290 nm for all the CN loads investigated (from 0 to 15% CN loading). The electrospinning process di...

Abstract Electrospinning is a contemporary and effective technique for producing fine fibers with diameters as small nanometers by using an electric field. These have numerous industrial applications, including filtration, sensors, composite materials, membranes. This study provides overview of the electrospinning process discusses few applications polyvinyl alcohol based electrospun nanofibers...

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...
